Re-Installing of Docker-APP (Mattermost and have the same settings as before



If I uninstall Mattermost or Rocket.Chat from the App Center and then reinstall it, the data from the previous installation will remain. how can I completely uninstall the apps and reinstall them without overinstalling them?


hm… I could swear that at some point this was documented within the Mattermost app (for example in the uninstall readme), but I cannot see this at the moment anymore.

UCS by default stores the app data in /var/lib/univention-appcenter/apps/. For Mattermost the directory to remove would be /var/lib/univention-appcenter/apps/mattermost.


thank you very much for this fast solution :slight_smile:
