Ubuntu is published on a six-month release cycle, withlong-term support (LTS) versions issued every two years.[18][19] Canonical provides security updates and support until each release reaches its designatedend-of-life (EOL), with optional extended support available through the Ubuntu Pro and Expanded Security Maintenance (ESM) services.[20][21]
Ubuntu can be installed directly on hardware or run within avirtual machine. It is widely used forcloud computing, with integration support for platforms such asOpenStack.[22] It is also one of the most popular Linux distributions for general desktop use,[23][24] supported by extensive online communities such asAsk Ubuntu, and has spawned numerous community-maintained variants.[25]
The name "Ubuntu" comes from theNguni philosophy ofubuntu, which translates roughly as "humanity to others" or "I am what I am because of who we all are".[9]
In April 2004,Mark Shuttleworth invited a dozenDebian developers to his London flat, where they brainstormed and laid out the distinguishing features of what would become Ubuntu. Shuttleworth chose the "Ubuntu" name for his South African roots and to emphasize community. To fund the project, Shuttleworth createdCanonical Ltd. to employ the developers[26] using his fortune from sellingThawte toVerisign.[27] For the first year, the company had no physical offices and employees used online platforms to coordinate, fostering transparency. The group set a six-month deadline and decided to only announce Ubuntu during its first release—October 2004: "Warty Warthog".[28]
On 8 July 2005, Shuttleworth and Canonical launched the newly-created Ubuntu Foundation and provided initial funding of US$10 million. The purpose of the foundation is to ensure the support anddevelopment for all future versions of Ubuntu. Mark Shuttleworth described the foundation's goal as to ensure the continuity of the Ubuntu project.[29]
On 12 March 2009, Ubuntu announced developer support for third-partycloud management platforms, such as those used atAmazon EC2.[30]
In 2011, Ubuntu's default desktop was changed fromGNOME 2 to the in-houseUnity instead ofGNOME 3.[31]
In 2014, Canonical announced Snappy Ubuntu Core, an immutable OS designed for use inembedded systems, along with its new package manager named "Snappy" derived from theUbuntu Phone project.[32] By the release of Ubuntu 16.04, the package management system was renamed "Snap" and supported desktop apps, becoming an alternative toFlatpak.[33]
After nearly 6.5 years, the default desktop was changed back to GNOME 3 in 2017, upon the release of version17.10.[34] Ubuntu, since version 16.04.5, requires a 2 GB or larger installation medium.[35][36] The last release of Ubuntu available on a minimal CD was 18.04.[37] 32-bitx86 processors were supported up to Ubuntu 18.04.[38] It was decided to support "legacy software", i.e. select32-bit i386 packages, for Ubuntu 19.10 (since out of support) and 20.04 LTS.[39]
In 2022, Ubuntu consolidated its extended security maintenance and hardening services into the Ubuntu Pro subscriptions, including LivePatch, a feature that allows devices to perform select security updates without reboots, available free-of-charge for personal use on up to five machines.[40]
In June 2023, Canonical announced Ubuntu Core Desktop, an immutable desktop OS, completely made ofsnap packages like Ubuntu Core and slated for release along Ubuntu 24.04 LTS.[41] Its release was indefinitely delayed, as the vision for major advantages had not yet been fully realized.[42]
After a rise in the popularity ofcryptocurrency scam packages, theSnap Store started requiring manual approval for new applications in March 2024.[43]
On 9 August 2024, Ubuntu announced a change in policy to always use the latest upstream version of theLinux kernel at the time of each Ubuntu release, even if the kernel code has not seen a stable release and is still inrelease candidate status.[44]
Support for theX11 windowing system was dropped in favour of the alternativeWayland, with Ubuntu version 25.10 in 2025, which shipped with GNOME 49 which had made the change.[45]
Ubuntu is built onDebian's architecture and infrastructure, and comprises Linux server, desktop, and discontinued phone and tablet operating system versions.[46] As of version 24.10, adefault installation of Ubuntu contains a minimal selection of software, namely a web browser (Firefox), and basicGNOME utilities (including the desktop).[47] Many additional software packages are accessible from the built-inUbuntu Software (previouslyUbuntu Software Center), as well as any other APT-basedpackage management tools. Many additional software packages that are no longer installed by default, such asEvolution,GIMP,Pidgin, andSynaptic, are still accessible in the repositories and installable by the main tool or by any other APT-based package management tool. Cross-distributionsnap packages andFlatpaks are also available,[48] that both allow installing software, such as some of Microsoft's software, in most of the major Linux operating systems (such as any currently supported Ubuntu version and inFedora). The default file manager isGNOME Files, formerly called Nautilus.[49][50]
All of the application software installed by default is free software. In addition, Ubuntu redistributes some hardware drivers that are available only in binary format, but such packages are clearly marked in the restricted component.[51]
Currentlong-term support (LTS) releases are supported for five years, and are released every two years. Since the release of Ubuntu 6.06, every fourth release receives long-term support.[52] Long-term support includes updates for new hardware, security patches, and updates to the 'Ubuntu stack' (cloud computing infrastructure).[53] The first LTS releases were supported for three years on the desktop and five years on the server; since Ubuntu 12.04 LTS, desktop support for LTS releases was increased to five years as well.[54][55][56] LTS releases get regular point releases with support for new hardware and integration of all the updates published in that series to date.[57]
Ubuntu packages are based onDebian's unstable branch, which are synchronized every six months.Both distributions use Debian'spackage management tools (e.g.APT andGNOME Software) anddeb format ofpackages.[citation needed] Debian and Ubuntu packages are not necessarilybinary compatible with each other, however, some packages may need to be rebuilt fromsource to be used in Ubuntu.[58] Many Ubuntu developers are also maintainers of key packages within Debian. Ubuntu cooperates with Debian by pushing changes back to Debian,[59] although there has been criticism that this does not happen often enough.Ian Murdock, the founder of Debian, had expressed concern about Ubuntu packages potentially diverging too far from Debian to remain compatible.[60] Before release, packages are imported fromDebian unstable continuously and merged with Ubuntu-specific modifications. At some point during the release process, the Debian Import Freeze is implemented. This prevents the automatic import of packages from Debian without an explicit request from a developer. In combination with other freezes, this helps packagers ensure that frozen features interoperate well together.[61][62]
All official Ubuntu packages are available from hundreds ofmirrors worldwide. As of March 30, 2025, there were a total of 617 Ubuntu mirrors operating.[63]
Ubuntu aims to be secure by default.[64][65] User programs run withlow privileges and cannot corrupt the operating system or other users' files. For increased security, thesudo tool is used to assign temporary privileges for performing administrative tasks, which allows theroot account to remain locked and helps prevent inexperienced users from inadvertently making catastrophic system changes or openingsecurity holes.[66]Polkit is also being widely implemented into the desktop.[citation needed]
Most network ports are closed by default to prevent hacking.[67] A built-infirewall,Uncomplicated Firewall, allows end-users who install network servers to control access. AGUI is available to configure it.[68] Ubuntu compiles its packages usingGCC features such asPIE andbuffer overflow protection toharden its software.[69][relevant? –discuss] These extra features greatly increase security at the performance expense of 0.01% in64-bit.[70]
Ubuntu also supports full disk encryption,[71] as well as encryption of the home and private directories.[72]
The system requirements vary among Ubuntu products. For the Ubuntu desktop release 22.04 LTS (and still for 24.04.1), a PC with at least 2 GHzdual-core processor, 4 GB ofRAM and 25 GB of free disk space is recommended.[73] For less powerful computers, there are other Ubuntu distributions such asLubuntu andXubuntu. Ubuntu also supports theARM architecture.[5][74][75][76][77] It is also available onPower ISA,[5][78][79][80] while olderPowerPC architecture was at one point unofficially supported,[81] and now newerPower ISA CPUs (POWER8) are supported. Thex86-64 ("AMD64") architecture is also officially supported.[5]
Live images are the typical way for users to assess and subsequently install Ubuntu.[10] These can be downloaded as a disk image (.iso) and subsequently burnt to a DVD or USB flash drive and then booted. Other methods include running the live version viaVentoy,UNetbootin,Universal USB Installer, or Startup Disk Creator (a pre-installed tool on Ubuntu, available on machines already running the OS) directly from a USB drive (making, respectively, alive DVD orlive USB medium). Running Ubuntu in this way is slower than running it from ahard drive, but does not alter the computer unless specifically instructed by the user. If the user chooses to boot the live image rather than execute an installer at boot time, there is still the option to then use the Ubuntu Desktop Installer once booted into the live environment.[82] The Ubuntu Desktop Installer replaced the formerUbiquity installer since Ubuntu 23.04.[83]Disk images of all current and past versions are available for download at the Ubuntu web site.[84]
Additionally,USB flash drive installations can be used to boot Ubuntu andKubuntu in a way that allows permanent saving of user settings and portability of the USB-installed system between physical machines (however, the computers'BIOS must support booting from USB).[85] In newer versions of Ubuntu, theUbuntu Live USB creator can be used to install Ubuntu on a USB drive (with or without a live CD or DVD). Creating a bootable USB drive withpersistence is as simple as dragging a slider to determine how much space to reserve for persistence; for this, Ubuntu employscasper.[86][87]
Ubuntu divides most software into four domains to reflect differences in licensing and the degree of support available.[88] Some unsupported applications receive updates from community members known as "Masters of the Universe" (MOTU).[89] Before January 2023, community supported free software inUniverse repository received no updates at all from Canonical Ltd. Since 26 January 2023, customers of the Ubuntu Pro subscription service—which is free for personal use[90]—can get Canonical-supported updates also for packages inUniverse repository.[91]
Non-free software is usually unsupported (Multiverse), but some exceptions (Restricted) are made for important non-free software and/or software potentially illegal in some territories. Supported non-free software includes device drivers that can be used to run Ubuntu on some current hardware, such as binary-onlygraphics carddrivers. The level of support in the Restricted category is more limited than that of Main, because the developers may not have access to thesource code. It is intended that Main and Restricted should contain all software needed for a completedesktop environment.[88]
In addition to the above, in which the softwaredoes not receive new features after an initial release,Ubuntu Backports is an officially recognised repository forbackporting newer software from later versions of Ubuntu.[93]
The-updates repository provides stable release updates (SRU) of Ubuntu and are generally installed through update-manager. Each release is given its own -updates repository (e.g. intrepid-updates). The repository is supported by Canonical Ltd. for packages in main and restricted, and by the community for packages in universe and multiverse. All updates to the repository must meet certain requirements and go through the-proposed repository before being made available to the public.[94]
In addition to the -updates repository, the unstable-proposed repository contains uploads that must be confirmed before being copied into -updates. All updates must go through this process to ensure that the patch does truly fix the bug and there is no risk ofregression.[95]
Canonical previously hosted a partner repository that let vendors of proprietary software deliver their products to Ubuntu users at no cost through the same familiar tools for installing and upgrading software.[96] The software in the partner repository was officially supported with security and other important updates by its respective vendors. Canonical supported the packaging of the software for Ubuntu[97][98][99] and provided guidance to vendors.[96] However, in anticipation for the release of Ubuntu 22.04 LTS Canonical closed the partner repository, as the only package still hosted in it wasAdobe Flash, which would not be released with 22.04.[100] Ubuntu developer Steve Langasek said in a development mailing list that he felt the "Snap Store has matured to the point that I believe it supersedes the partner archive".[101]
APersonal Package Archive (PPA) is asoftware repository for uploading source packages to be built and published as anAdvanced Packaging Tool (APT) repository by Canonical'sLaunchpad service.[102] While the term is used exclusively within Ubuntu,Canonical, envisions adoption beyond the Ubuntu community.[103]
Some third-party software that does not limit distribution is included in Ubuntu's multiverse component. The packageubuntu-restricted-extras additionally contains software that may be legally restricted, including support forDVD playback,Microsoft TrueType core fonts, many common audio/videocodecs, and unrar, an unarchiver for files compressed in theRAR file format.[104]
Additionally, third-party application suites are available for download via Ubuntu Software and theSnap store,[105] including many games such asBraid,Minecraft andOil Rush,[106] software for DVD playback and media codecs.[107]
Ubuntu follows a time-based release cycle, issuing new versions every six months.[52] Each standard release receives nine months of free support, including security updates and high-impact bug fixes.[120][121][122]
Every fourth release, occurring in the second quarter of even-numbered years, is designated along-term support (LTS) release.[123] LTS releases receive five years of free support, with the option to extend support up to ten years through the Expanded Security Maintenance (ESM) program, available through the Ubuntu Pro subscriptions,[124][125][126] which are free for personal use.[90]
Ubuntu version numbers reflect the year and month of release. For example, Ubuntu 4.10 was released in October 2004.[127]
Each release also has an alliterativecode name, typically consisting of an adjective and an animal (e.g., "Bionic Beaver").[128] Releases are often referred to by the adjective alone.[129]
Ubuntu releases are typically scheduled about one month after correspondingGNOME releases.[130][131][132]
Ubuntu Desktop (formally named as Ubuntu Desktop Edition, and simply called Ubuntu) is the variant officially recommended for most users. It is designed for desktop and laptop PCs and is officially supported by Canonical. Variants are distinguished simply by each featuring a differentdesktop environment, or, in the case of Ubuntu Server, no desktop.[84]LXQt andXfce[133] are often recommended for use with older PCs that may have less memory and processing power available.[citation needed]
Most Ubuntu editions and flavours simply install a different set of default packages compared to the standard Ubuntu Desktop. Since they share the same package repositories, all of the same software is available for each of them.[134][135] Ubuntu Core[a] is the sole exception as it only has access to packages in theSnap Store.[136]
Edubuntu, formerly Ubuntu Education Edition, is a flavour of Ubuntu that has been modified for education. It is designed forpreschool,primary,secondary andtertiary educations through the installation of different packages.
Lubuntu is an Ubuntu flavour that is "lighter, less resource hungry and more energy-efficient", using theLXQtdesktop environment (usedLXDE before 18.10).[138][139][140]
Ubuntu Core
An Ubuntu edition focused on IoT and embedded systems. It has no graphical interface, and only allows access over SSH. Unlike other variants, it does not use the traditional apt package manager but relies entirely onSnap packages.[136] It is designed to be configured viamodel assertions which are text documents defining which Snap packages and configurations apply to the OS image.[141]
An Ubuntu flavour usingMATE, a desktop environment forked from the now-defunct GNOME 2 code base, with an emphasis on thedesktop metaphor.[144]
Ubuntu Server
Ubuntu has aserver edition[145][146] that uses the same APT repositories as the Ubuntu Desktop Edition. The differences between them are the absence of anX Window environment in a default installation of the server edition (although one can easily be installed, including GNOME, KDE, Unity or Xfce), and some alterations to the installation process.[147] The server edition uses a screen-mode,character-based interface for the installation, instead of a graphical installation process. This enables installation on machines with a serial or "dumb terminal" interface without graphics support.
It has versions of key server software pre-installed, including Tomcat, PostgreSQL (v12.2), Docker, Puppet, Python (v3.9), PHP (v8.0), NGINX (v1.17), and MySQL (v8.0).
Based on Ubuntu, providing open-source applications for multimedia creation aimed at the audio, video and graphic editors. This release uses theKDE Plasma 5 desktop environment; previous releases usedXfce.[154]
An Ubuntu flavour usingXfce. Xubuntu is intended for use on less-powerful computers or those who seek a highly efficient desktop environment on faster systems, and uses mostlyGTK applications.[158]
Ubuntu had some official distributions that have been discontinued, such asGobuntu; including some previously supported by Canonical, likeUbuntu Touch, that is now maintained by volunteers (UBports Community).
Alongside the official flavours are those that are unofficial. These are still in the process of becoming recognised as official flavours by Canonical.[159][160]
Ubuntu offers Ubuntu Cloud Images which are pre-installed disk images that have been customised by Ubuntu engineering to run on cloud-platforms such asAmazon EC2,OpenStack,Microsoft Azure andLXC.[164] Ubuntu is also prevalent onVPS platforms such asDigitalOcean.[165]
Eucalyptus interface
Ubuntu has support for OpenStack, with Eucalyptus to OpenStack migration tools added by Canonical.[166][167]Ubuntu 11.10 added focus on OpenStack as the Ubuntu's preferredIaaS offering, though Eucalyptus is also supported. Another major focus isCanonical Juju for provisioning, deploying, hosting, managing, and orchestrating enterprise data centre infrastructure services, by, with, and for the Ubuntu Server.[168][169]
Ubuntu was awarded the Reader Award for best Linux distribution at the 2005LinuxWorld Conference and Expo in London,[170] received favourable reviews in online and print publications,[171][172] and has wonInfoWorld's 2007 Bossie Award forBest Open Source Client OS.[173] In early 2008,PC World named Ubuntu the "best all-around Linux distribution available today", though it criticized the lack of an integrated desktop effects manager.[174] Chris DiBona, the program manager for open-source software at Google, said "I think Ubuntu has captured people's imaginations around the Linux desktop," and "If there is a hope for the Linux desktop, it would be them". As of January 2009[update], almost half of Google's 20,000 employees usedGoobuntu, a slightly modified version of Ubuntu.[175] In 2012,ZDNet reported that Ubuntu was still Google's desktop of choice.[176] In March 2016, Matt Hartley picked a list of best Linux distributions forDatamation; he chose Ubuntu as number one.[177]
In January 2014, the UK's authority for computer security,CESG, reported thatUbuntu 12.04 LTS was "the only operating system that passes as many as 9 out of 12 requirements without any significant risks", though it was unclear if any other Linux distributions were tested.[181]
As Ubuntu is distributed freely and historically, there was no registration process (still optional[182][183]), Ubuntu usage can only be roughly estimated.[184] In 2015, Canonical's Ubuntu Insights page stated, "Ubuntu now has over 40 million desktop users and counting".[185]
W3Techs Web Technology Surveys estimated in November 2020 that:
Ubuntu is by far the most popularLinux distribution for runningweb servers; of the websites they analyse it is "used by 47.3% of all the websites who use Linux",[186] and Ubuntu alone powers more websites thanMicrosoft Windows, which powers 28.2% of all websites, or 39% of the share Unix has (which includes Linux and thus Ubuntu). All Linux/Unix distributions in total power well over twice the number of hosts as Windows for websites based on W3Techs numbers. Ubuntu and Debian only (which Ubuntu is based on, with the same package manager and thus administered the same way) make up 65% of all Linux distributions for web serving use; the usage of Ubuntu surpassed Debian (for suchserver use) in May 2016.[citation needed]
Ubuntu is the most popular Linux distribution among the top 1,000 sites and gains around 500 of the top 10 million websites per day.[187]
W3Techs analyses the top 10 million websites only.[188]
Wikimedia Foundation data (based onuser agent) for September 2013 shows that Ubuntu generated the most page requests to Wikimedia sites, including Wikipedia, among recognizable Linux distributions.[189][190]
As of October 2025[update], Ubuntu 22.04 is used in Microsoft NDv5, aMicrosoft's Azure cloud computer, its fastest one (of 7 Azure supercomputers, all running on Ubuntu), still fastest ever Microsoft computer, currently 5th fastest, previously in November 2024, 3rd fastestsupercomputer on theTOP500 list (only then beaten by the then only two exaflop computers; is itself half anexaflop, only the then top 3 were that powerful).[191] Other supercomputers running Ubuntu also rank high on the list e.g. NVIDIA's Selene supercomputer still ranks highly, and was fifth-fastest one in the world in November 2022[192] after an upgrade from seventh place, where it entered the list in June. Another Nvidia-based supercomputer using Ubuntu previously topped theGreen500 list (it and the next one was also Ubuntu-based), a list which is a reordering of former list, ordered by power-efficiency.[193] On the TOP500 list, that supercomputer was ranked 170nd (and many Ubuntu-based rank higher than that).[194]
The public sector has also adopted Ubuntu. As of January 2009[update], the Ministry of Education and Science ofNorth Macedonia deployed more than 180,000[175] Ubuntu-based classroom desktops, and has encouraged every student in the country to use Ubuntu-powered computer workstations;[195] the Spanish school system has 195,000 Ubuntu desktops.[175] The French police, having already started usingopen-source software in 2005 by replacingMicrosoft Office withOpenOffice.org, decided to transition to Ubuntu fromWindows XP after the release ofWindows Vista in 2006.[196] By March 2009, theGendarmerie Nationale had already switched 5,000 workstations to Ubuntu.[196] Based on the success of that transition, it planned to switch 15,000 more over by the end of 2009 and to have switched all 90,000 workstations over by 2015(GendBuntu project).[196] Lt. Colonel Guimard announced that the move was very easy and allowed for a 70% saving on the IT budget without having to reduce its capabilities.[196] In 2011, Ubuntu 10.04 was adopted by the Indian justice system.[197]
In 2004,[198] the city ofMunich, Germany, started theLiMux project, and later forked Kubuntu 10.04 LTS for use on the city's computers.[199] After originally planning to migrate 12,000 desktop computers to LiMux, it was announced in December 2013 that the project had completed successfully with the migration of 14,800 out of 15,500 desktop computers,[200] but still keeping about 5,000 Windows clients for unported applications. In February 2017 the majority coalition decided, against heavy protest from the opposition,[201] to evaluate the migration back to Windows,[202] after Microsoft had decided to move its company headquarters to Munich.[203] Governing MayorDieter Reiter cited lack of compatibility with systems outside of the administrative sector, such as requiring a governmentalmail server to send e-mails to his personalsmartphone, as reasons for the return, but has been criticised for evaluating administrative IT based on private and business standards.[204] In May 2020, the recently electedAlliance 90/The Greens party and theSocial Democrat party negotiated a new coalition agreement, stating: "Where it is technologically and financially possible, the city will emphasize open standards and free open-source licensed software".[205][206]
In March 2012, the government of Iceland launched a project to get all public institutions using free and open-source software. Already, several government agencies and schools have adopted Ubuntu. The government cited cost savings as a big factor for the decision, and also stated that open-source software avoidsvendor lock-in. A 12-month project was launched to migrate the biggest public institutions in Iceland to using open-source software, and help ease the migration for others.[207] US presidentBarack Obama's successfulcampaign for re-election in 2012 used Ubuntu in its IT department.[208] In August 2014, the city ofTurin, Italy, announced its migration fromWindows XP to Ubuntu for the 8,300 desktop computers used by the municipality, becoming the first city in Italy to adopt Ubuntu.[209][210]
Starting in 2008, theWikimedia Foundation, the non-profit organization behindWikipedia, switched from multiple different Linux operating systems to Ubuntu[211][212] (in 2019, it switched again, from Ubuntu toDebian).[213]
In June 2019, Canonical announced that they would be deprecating support for32-bit applications and libraries in Ubuntu 19.10.[214]
BecauseSteam's Linux client depends on these 32-bit libraries,Valve announced that they would no longer be supporting Ubuntu. After uproar from the Linux gaming community, Canonical backtracked on this decision and decided to support select 32-bit libraries. As a result, Valve decided that Steam would support Ubuntu 19.10 again.[215][216]
Wine needs most of the same 32-bit library packages that the Steam package depends on, and more, to enable its version ofWoW64 to run 32-bit Windows applications. The parts of Wine that would continue to function without 32-bit libraries would be limited to the subset of Windows applications that have a 64-bit version, removing decades of Windows compatibility. In Canonical's statement on bringing back the libraries, they mentioned using "container technology" in the future to make sure that Wine continues to function.[217]
Soon after being introduced in 2012, doubts emerged on the conformance of theshopping lens (a feature that displays Amazon suggestions in the searching toolUnity Dash) with the EuropeanData Protection Directive.[218][219] A petition was later signed and delivered to Canonical demanding various modifications[example needed] to the feature to clearly frame it within European law. Canonical did not reply.[citation needed]
In 2013, a formal complaint on the shopping lens was filed with theInformation Commissioner's Office (ICO), the UK data privacy office. Almost one year later, the ICO ruled in favour of Canonical, considering the various improvements introduced to the feature conformed with theData Protection Directive.[220] According to European rules, this ruling is automatically effective in the entirety of the European Union. However, the ruling also made clear that at the time of introduction the feature was not legal, among other things, since it was missing a privacy policy statement.[citation needed]
Ubuntu has integrated increasing quantities of advertising into the operating system's terminal, leading to multiple controversies with its user base.[citation needed]
In 2017, Canonical placed a message regarding HBO's Silicon Valley in theMOTD file, causing the message to be shown whenever a terminal session started. Over the following years, more messages would be placed into the MOTD.[221]
In 2022, ads for Ubuntu's premium service, Ubuntu Advantage, were introduced into the apt system update utility. This move caused controversy in the user community, with some users considering advertising a fair business model to support development, while other users found the inclusion inappropriate and annoying.[222]
To reach out to users who are less technical, and to foster a sense of community around the distribution, Local Communities,[223] better known as "LoCos", have been established throughout the world. Originally, each country had one LoCo Team. However, in some areas, most notably the United States and Canada, each state or province may establish a team.[224] A LoCo Council approves teams based upon their efforts to aid in either the development or the promotion of Ubuntu.[225]
Ubuntu has received broad support from hardware vendors, with several manufacturers offering computers pre-installed with the operating system. Canonical collaborates with original equipment manufacturers (OEMs) to certify and support Ubuntu on a variety of devices,[226] primarily targeting enterprise and developer markets.[227]
Major OEMs such as Dell, Lenovo, and HP have offered laptops and desktops with Ubuntu as an alternative to Windows, often through online configuration options or regional sales channels.[228][229] Ubuntu is also offered on theIBM Z series of mainframes.[230][231]
Smaller vendors such asSystem76 and OnLogic also ship systems with Ubuntu pre-installed, sometimes offering firmware customization or support options through Canonical.[232][233]
ManyWindows applications can be run on Ubuntu, much like in other Linux distributions, using theWine compatibility layer, which can be managed via frontends such asBottles.
Steam has a Windows compatibility layer calledProton, and it has derivatives such asGE-Proton.
Multiple Windows virtual machines can also be installed by KVM/QEMU and Virt-Manager.[234] Graphics settings are easiest in QXL/SPICE mode. For 3D accelerated graphics performance, there is a third-party VirGL driver or GPU Full Passthrough mode.
In a networked environment, file sharing between Ubuntu Linux and Windows is possible bySamba client/server software. Host Ubuntu Linux and the guest Windows virtual machines are also virtually networked in KVM, so file sharing between the host and virtual guest machines can also be done by the Samba in theKVM environment.
RDP server of GNOME Remote Desktop andRemmina client software is used for remote desktop connection between Ubuntu Linux and the other OSs.
In 2019, Microsoft announced the newWSL 2 subsystem that includes aLinux kernel, that Canonical announced will have "full support for Ubuntu".[240] By this time, it was possible to run graphical Linux apps on Windows.[241] In 2021, Microsoft went on to add out-of-the-box support for graphical Linux apps, through the WSLg project.[242][243]
In May 2021, Microsoft extended its Threat and Vulnerability Management solution, which was a Windows-only solution thus far, to support Ubuntu, RHEL, and CentOS.[244] Starting with version 6,PowerShell runs on Ubuntu and can manage both Windows and Ubuntu computers remotely from either platforms.[citation needed]
