*DNF* is a software package manager that installs, updates, and removes
|
|
link:package[packages] on RPM-based Linux distributions. 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).

Installation
|
|
~~~~~~~~~~~~
|
|
|
|
DNF comes with Fedora since version 18, but DNF can installed by using
|
|
the yum Command:
|
|
|
|
....
|
|
# yum install dnf
|
|
....
|
|
|
|
As of Fedora 22, yum has been replaced with DNF and doesn't need to be
|
|
install.
|
|
|
|
[[usage]]
|
|
Usage
|
|
~~~~~
|
|
|
|
In the basic methods, DNF can be used almost exactly as yum to search,
|
|
install or remove packages:
|
|
|
|
....
|
|
# dnf search audacity
|
|
....
|
|
|
|
....
|
|
# dnf install audacity
|
|
....
|
|
|
|
....
|
|
# dnf remove audacity
|
|
....
|

monitor and report via email availability of updates, or send a log
|
|
