DNF (abbreviation forDandified YUM)[7][8][9] is apackage manager forRed Hat-basedLinuxdistributions and derivatives. DNF was introduced inFedora 18 in 2013 as a replacement foryum;[10] it has been the default package manager sinceFedora 22 in 2015[11] andRed Hat Enterprise Linux 8 in 2019[12] and is also an alternative package manager forMageia. DNF performs package management tasks on top ofRPM, and supporting libraries.
The DNF package manager works similarly to other package managers.[13] Its core usage works very similarly to theApt Package Manager, such asinstall,remove, andupgrade.[14][13]
Usage for basic command is as follows:[13]
sudo dnf install <package_name>
sudo dnf remove <package_name>
sudo dnf upgrade

Perceived deficiencies of yum (which DNF is intended to address) include poor performance, high memory usage, and the slowness of its iterativedependency resolution.[15] DNF useslibsolv, an external dependency resolver (developed byopenSUSE).[15]
DNF was originally written inPython, but as of 2016[update], efforts were under way to port it toC and move most functionality from Python code into the new libdnf library[needs update].[16] In 2018, the DNF team announced the decision to move libdnf from C toC++.[17][18] libdnf is already used byPackageKit, aLinux distribution-agnostic package system abstraction library, even though the library doesn't have most of DNF's features.[19]
Since the launch of Fedora Linux 41, DNF5 is the new default packaging tool. This release features new performance enhancements, updated terminal output, and fully integrated modularity.[20]
DNF has been the default command-line package manager for Fedora since version 22, which was released in May 2015.[11] The libdnf library is used as a package backend inPackageKit,[19] which offers a graphical user interface (GUI). Later, dnfdragora was developed for Fedora 27 as another alternative graphical front-end of DNF.[21][22] DNF has also been available as an alternate package manager forMageia Linux since version 6 and may become the default sometime in the future.[23]
In Red Hat Enterprise Linux, and by extension, AlmaLinux and Rocky Linux,yum is an alias for dnf.[12]
