dnf-automatic - DNF Automatic
Синопсис (Synopsis)
dnf-automatic [<config file>]
Описание (Description)
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.
RUN DNF-AUTOMATIC
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.
