It automatically computes dependencies and determines the actions required to install packages. DNF also makes it easier to maintain groups of machines, eliminating the need to manually update each one using rpm. Introduced in Fedora 18, it has been the default package manager since Fedora 22. DNF or Dandified yum is the next generation version of yum. It roughly maintains CLI compatibility with yum and defines a strict API for extensions and plugins. Plugins can modify or extend features of DNF or provide additional CLI commands on top of those mentioned below. If you know the name of such a command (including commands mentioned bellow), you may find/install the package which provides it using the appropriate virtual provide in the form of dnf-command() where is the name of the command; e.g. dnf-command(repoquery) for a repoquery command (the same applies to specifying dependencies of packages that require a particular command). [[features]] Features ~~~~~~~~ * Support for multiple repositories * Simple configuration * Dependency calculation based on modern depsolving technology * Faster and less memory-intensive operation * RPM-consistent behavior * Package group support, including multiple-repository groups * Simple interface * Documented, solid Python API * DNF runs in both Python 2 and Python 3 * C bindings for lower level libraries: ** hawkey for package querying and depsolving. PackageKit is already making use of hawkey ** librepo for repo operations. PackageKit is already making use of librepo ** libcomps for comps operations [[available-commands]] Available commands ~~~~~~~~~~~~~~~~~~ autoremove check-update clean distro-sync downgrade group help history info install list makecache mark provides reinstall remove repolist repository-packages search updateinfo upgrade upgrade-to [[installation]] Installation ~~~~~~~~~~~~ DNF comes with Fedora since version 18, but DNF can installed by using the yum Command: .... # yum install dnf ....
