Software & Update Management
openmediavault is a Debian based distribution. It uses APT to install packages. All standard Debian packages are upgraded using the official Debian mirrors. openmediavault packages are upgraded using the https://packages.openmediavault.org repository.
Package updates will be displayed under
System | Update Management | Updates
in the web interface. There you can view the changelog of individual packages or install
all packages at once.
cron-apt is used by openmediavault to perform a daily scheduled job
to check for new package updates. Security updates will be installed automatically
in the background. If you have notifications enabled you will receive an email
every time packages are ready for installation.
This is non-interactive wrapper script that basically re-synchronizes the package index files from their sources and installs the newest versions of all packages currently installed on the system.
This is a script which is included only in the last versions of openmediavault before moving to the next major release version, e.g. 5.6.x to 6.x. This command migrates the system to the next major openmediavault version (which mostly includes a Debian distribution upgrade as well).
Plugins can be installed via the web interface or CLI. If the plugin requires some extra software, the Debian package management will fetch all dependencies from the configured Debian package repositories.
You can install all software available in the Debian repositories on your server.
Please note that the installation of additional software may impair
or prevent the functionality of openmediavault. This includes especially the
installation of newer Python package versions via PIP which have
already been installed via APT. Also, please do not install packages
as this may install incompatible package versions. openmediavault is strictly
tied to the Debian version it is based on.
Better use a container based solution to install additional software to do not affect the openmediavault operating system.
Do not install the
apache webserver package, this leads to the
uninstallation of the
openmediavault package and the unusability
of the system.
$ apt-get install <packagename>
$ apt-get remove <packagename>
Purge (remove package and configuration files):
$ apt-get purge <packagename>
The OS repositories are in this file
Debian provides the
/etc/apt/sources.list.d/ folder for adding external
repositories. The configuration files for the openmediavault package repositories
are located here.
If there is a strong need to add the
Experimental Debian repository just to install the most recent
software, then please ensure that these packages are properly pinned
 to avoid the system becoming unstable for adding core unsupported
software by mistake.
