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.
The update manager displays all available packages for upgrade. You can select
them if you want to do individual or mass upgrade. The server uses
perform a daily
apt-get update and fetch upgrade packages automatically. If you
have notifications enabled you will receive an email every time packages are ready
If you want to update/upgrade in the console you can use
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 from the sources.
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.
$ apt-get install <packagename>
$ apt-get remove <packagename>
Purge (remove package and configuration files):
$ apt-get purge <packagename>

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.
