Nextcloud Upgrade endup with all data lost

Apps & App Center
#1

Hello,
I’m completely in deep shit, I executed today update of nextloud from .5 to .7 which finished as failure but after that seams fine, but after reboot all data are gone I can access gui but looks like fresh installation. even in folder /var/lib/univention-appcenter/apps/nextcloud/data are no data just that default one and df -h shows me sad info that I have lot of free space. Guys I’m lost I don’t have any idea where to start. I simply cant belive that even failing upgrade can cause such drastic data loss…
Any idea is more than wellcome

New Instalation after update
#3

This looks very bad indeed :frowning:

Nextcloud is not installed - only a limited number of commands are available

This indicates that the config.php

  • was modifed (→ the installed flag removed)
  • was overwritten by /var/lib/univention-appcenter/apps/nextcloud/conf/config/config.php (this happens, the config file is being backuped up thereto after setup run and before upgrade happens) which had this flag missing
  • or the whole file itself removed

There is no part in the scripts however where the config file is modified in such a way.

On uninstall, the app folder is being removed. I agree, that’s not what one would expect to happen on a failed update. :frowning:
