The fix needs to be merged to UCS 4.2.

+++ This bug was initially created as a clone of Bug #42450 +++

We found in /etc/apt/sources.list.d/15_ucs-online-version.list

# An error occurred during the repository check. The error message:
#   Traceback (most recent call last):

Only 4.1-3-errata was included in 20_ucs-online-component.list

This resulted in the following apt-get operation set:

Die folgenden Pakete werden ENTFERNT:
  univention-management-console univention-management-console-module-setup
  univention-server-master

  python-univention-appcenter
Die folgenden Pakete werden aktualisiert (Upgrade):

  [...]

The problem came from added dependencies in univention-management-console-module-setup and python-univention-appcenter in the latest 4.1-3 errata updates. These dependencies could not be found and thus the packages were not installed / had to be removed.

The updater should not operate under these conditions. Also, the sources.list should rewrite itself. We got feedback that later on, the error messages disappeared.
