How to repair kopano installation after being destroyed by nextcloud installation

UCS - Univention Corporate Server
,
#1

I installed nextcloud on UCS 8.7.7. All went well (no errors) except - nextcloud didn’t work.
Instead: my Kopano users complained about Kopano no longer working.
So I deinstalled nextcoud.
My configuration:

[UCS-Kopano 2019-12-05 19:44:23 root ~]# service kopano-server status
● kopano-server.service
   Loaded: masked (/dev/null; bad)

[UCS-Kopano 2019-12-05 19:44:37 root ~]# systemctl restart kopano-server.service
Failed to restart kopano-server.service: Unit kopano-server.service is masked.

My question: how can I repair the kopano server installation without loosing my users’ data?

I have listed steps to reinstall the packages at Kopano is not running anymore and https://forum.kopano.io/topic/2832/resolved-univention-password-change-not-forwarded-to-kopano-server

#3

The root cause for Kopano being destroyed is definitely the WUI installation of nextcloud. As described elsewhere some aggressive apt cleanup ruins the whole repository structure:

I’m not used to debian apt, but something like --auto-remove doesn’t sound goot to me.

I followed the steps decribed in https://help.univention.com/t/kopano-is-not-running-anymore/13783. Unfortunately the procedure failed:
