Problem:
The Installation of a new School Replica failes due to join problems. The symptoms can be different, sometimes a failed.ldif comes up or dpkg shows package or configuration issues.
Environment:
Primary, with already configured UCS@school app. Already successful installaed and joined school-replicas.
Solution:
First install the server without the initial join during installation, and do the join afterwards. This prevents a completely failing installation, and join problems can much better be debugged.
