DNF (abbreviation for Dandified YUM)[7][8][9] is a package manager for Red Hat-based Linux distributions and derivatives. DNF was introduced in Fedora 18 in 2013 as a replacement for yum;[10] it has been the default package manager since Fedora 22 in 2015[11] and Red Hat Enterprise Linux 8 [when?][12] and is also an alternative package manager for Mageia. DNF performs package management tasks on top of RPM, and supporting libraries.

History

[edit]

Perceived deficiencies of yum (which DNF is intended to address) include poor performance, high memory usage, and the slowness of its iterative dependency resolution.[13] DNF uses libsolv, an external dependency resolver.[13]

DNF was originally written in Python, but as of 2016 efforts were under way to port it to C and move most functionality from Python code into the new libdnf library[needs update].[14] In 2018, the DNF team announced the decision to move libdnf from C to C++.[15][16] libdnf is already used by PackageKit, a Linux distribution-agnostic package system abstraction library, even though the library does not have most of DNF's features.[17]

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.[18]

Adoption

[edit]

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 in PackageKit,[17] which offers a graphical user interface (GUI). Later dnfdragora was developed for Fedora 27 as another alternative graphical front-end of DNF.[19][20] DNF has also been available as an alternate package manager for Mageia Linux since version 6 and may become the default sometime in the future.[21]

In Red Hat Enterprise Linux, and by extension, AlmaLinux and Rocky Linux, yum is an alias for dnf.[12]
