bullseyereleased
August 14th, 2021
After 2 years, 1 month, and 9 days of development, the Debianproject is proud to present its new stable version 11 (code namebullseye
),which will be supported for the next 5 years thanks to the combined work of theDebian Security teamand theDebian Long Term Support team.
Debian 11bullseye
ships with several desktop applications andenvironments. Amongst others it now includes the desktop environments:
This release contains over 11,294 new packages for a total count of 59,551packages, along with a significant reduction of over 9,519 packages which were marked asobsolete
and removed. 42,821 packages were updated and 5,434 packages remainedunchanged.
bullseye
becomes our first release to provide a Linux kernel with support for theexFAT filesystem and defaults to using it for mount exFAT filesystems.Consequently it is no longer required to use the filesystem-in-userspaceimplementation provided via the exfat-fuse package. Tools for creatingand checking an exFAT filesystem are provided in the exfatprogs package.
Most modern printers are able to use driverless printing and scanning withoutthe need for vendor specific (often non-free) drivers.bullseye
brings forward a new package, ipp-usb, which uses the vendor neutralIPP-over-USB protocol supported by many modern printers. This allows a USBdevice to be treated as a network device. The official SANE driverless backendis provided by sane-escl in libsane1, which uses the eSCL protocol.
Systemd inbullseye
activates its persistent journal functionality, by default,with an implicit fallback to volatile storage. This allows users that are notrelying on special features to uninstall traditional logging daemons andswitch over to using only the systemd journal.
The Debian Med team has been taking part in the fight against COVID-19by packaging software for researching the virus on the sequence leveland for fighting the pandemic with the tools used in epidemiology; this workwill continue with focus on machine learning tools for both fields. The team'swork with Quality Assurance and Continuous integration is critical to theconsistent reproducible results required in the sciences.Debian Med Blend has a range of performance critical applications which nowbenefit from SIMD Everywhere. To install packages maintained by the Debian Medteam, install the metapackages named med-*, which are at version 3.6.x.
Chinese, Japanese, Korean, and many other languages now have a new Fcitx 5 inputmethod, which is the successor of the popular Fcitx4 inbuster
; this new versionhas much better Wayland (default display manager) addon support.
Debian 11bullseye
includes numerous updated software packages (over72% of all packages in the previous release), such as:
With this broad selection of packages and its traditional widearchitecture support, Debian once again stays true to its goal of beingThe Universal Operating System
. It is suitable for many different usecases: from desktop systems to netbooks; from development servers tocluster systems; and for database, web, and storage servers. At the sametime, additional quality assurance efforts like automatic installationand upgrade tests for all packages in Debian's archive ensure thatbullseye
fulfills the high expectations that users have of astable Debian release.
A total of nine architectures are supported:64-bit PC / Intel EM64T / x86-64 (amd64),32-bit PC / Intel IA-32 (i386),64-bit little-endian Motorola/IBM PowerPC (ppc64el),64-bit IBM S/390 (s390x),for ARM,armelandarmhf for older and more recent 32-bit hardware,plusarm64 for the 64-bitAArch64
architecture,and for MIPS,mipsel (little-endian) architectures for 32-bit hardwareandmips64el architecture for 64-bit little-endian hardware.
If you simply want to try Debian 11bullseye
without installing it,you can use one of the availablelive images which load and run thecomplete operating system in a read-only state via your computer's memory.
These live images are provided for theamd64 andi386 architectures and are available for DVDs, USB sticks,and netboot setups. The user can choose among different desktopenvironments to try: GNOME, KDE Plasma, LXDE, LXQt, MATE, and Xfce.Debian Livebullseye
has a standard live image, so it is also possibleto try a base Debian system without any of the graphical user interfaces.
Should you enjoy the operating system you have the option of installingfrom the live image onto your computer's hard disk. The live imageincludes the Calamares independent installer as well as the standard Debian Installer.More information is available in therelease notes and thelive install images sections ofthe Debian website.
To install Debian 11bullseye
directly onto yourcomputer's hard disk you can choose from a variety of installation mediasuch as Blu-ray Disc, DVD, CD, USB stick, or via a network connection.Several desktop environments — Cinnamon, GNOME, KDE Plasma Desktop andApplications, LXDE, LXQt, MATE and Xfce — may be installed through thoseimages.In addition,multi-architecture
CDs are available which supportinstallation from a choice of architectures from a single disc. Or you canalways create bootable USB installation media(see theInstallation Guidefor more details).
There has been a lot of development on the Debian Installer,resulting in improved hardware support and other new features.
In some cases, a successful installation can still have display issueswhen rebooting into the installed system; for those cases there area few workaroundsthat might help log in anyway.There is also anisenkram-based procedurewhich lets users detect and fix missing firmware on their systems,in an automated fashion. Of course, one has to weigh the pros andcons of using that tool since it's very likely that it will needto install non-free packages.
In addition to this, thenon-free installer images that include firmware packages have been improved so that they can anticipate the need for firmware in the installed system (e.g. firmware for AMD or Nvidia graphics cards, or newer generations of Intel audio hardware).
For cloud users, Debian offers direct support for many of thebest-known cloud platforms. Official Debian images are easilyselected through each image marketplace. Debian also publishespre-builtOpenStack images for theamd64 andarm64architectures, ready to download and use in local cloud setups.
Debian can now be installed in 76 languages, with most of them availablein both text-based and graphical user interfaces.
The installation images may be downloaded right now viabittorrent (the recommended method),jigdo, orHTTP; seeDebian on CDs for further information.bullseye
willsoon be available on physical DVD, CD-ROM, and Blu-ray Discs fromnumerousvendors too.
Upgrades to Debian 11 from the previous release, Debian 10(code namebuster
) are automatically handled by the APTpackage management tool for most configurations.
For bullseye, the security suite is now named bullseye-securityand users should adapt their APT source-list files accordingly when upgrading.If your APT configuration also involves pinning orAPT::Default-Release,it is likely to require adjustments too. See theChanged security archive layoutsection of the release notes for more details.
If you are upgrading remotely, be aware of the sectionNo new SSH connections possible during upgrade.
As always, Debian systems may be upgraded painlessly, in place,without any forced downtime, but it is strongly recommended to readtherelease notes aswell as theinstallationguide for possible issues, and for detailed instructions oninstalling and upgrading. The release notes will be further improved andtranslated to additional languages in the weeks after the release.
Debian is a free operating system, developed bythousands of volunteers from all over the world who collaborate via theInternet. The Debian project's key strengths are its volunteer base, itsdedication to the Debian Social Contract and Free Software, and itscommitment to provide the best operating system possible. This newrelease is another important step in that direction.
