dnf-automatic - DNF Automatic
dnf-automatic [<config file>]
Alternative CLI to dnf upgrade with specific facilities to make it
suitable to be executed automatically and regularly from systemd
timers, cron jobs and similar.
The operation of the tool is usually controlled by the configuration
file or the function-specific timer units (see below). The command
only accepts a single optional argument pointing to the config file,
and some control arguments intended for use by the services that back
the timer units. If no configuration file is passed from the command
line, /etc/dnf/automatic.conf is used.
The tool synchronizes package metadata as needed and then checks for
updates available for the given system and then either exits,
downloads the packages or downloads and applies the packages. The
outcome of the operation is then reported by a selected mechanism,
for instance via the standard output, email or MOTD messages.
The systemd timer unit dnf-automatic.timer will behave as the
configuration file specifies (see below) with regard to whether to
download and apply updates. Some other timer units are provided which
override the configuration file with some standard behaviours:
· dnf-automatic-notifyonly
· dnf-automatic-download
· dnf-automatic-install
Regardless of the configuration file settings, the first will only
notify of available updates. The second will download, but not
install them. The third will download and install them.
You can select one that most closely fits your needs, customize
/etc/dnf/automatic.conf for any specific behaviors, and enable the
timer unit.
For example: systemctl enable --now dnf-automatic-notifyonly.timer
The configuration file is separated into topical sections.
