Description Michael Grandjean

I assume this is an App Center bug, because the dependencies in debian/control of kopano4ucs* look fine, imho (https://stash.z-hub.io/projects/K4U/repos/kopano4ucs/browse/debian/control).

How to reproduce:

# "univention-app info" on Master:
UCS: 4.3-1 errata202
Installed: mailserver=12.0
Upgradable:

# "univention-app info" on Slave:
UCS: 4.3-1 errata202
Installed:
Upgradable:

1. Open the App Center module on the Slave
2. Try to install "Kopano Core" on the Slave
3. The dry-runs should look fine
4. Actually start the installation
5. The installation stalls around 50%

What actually happens:
-> kopano4ucs-{lib,schema,udm} is going to be installed on the Master
-> For some reason, the package conflicts of Kopano Core / "kopano4ucs" are checked (not the conflicts of kopano4ucs-{lib,schema,udm})
-> If the UCS Mailstack is installed on the Master, a package conflict is detected and the installation aborts

On the Slave:
