W: Failure while configuring required packages.

Hi, just a quick heads up: the buildscripts in univention-docker-dev should create common-docker files dynamically. For UCS 4.2 we need to adjust a script that is run by these dockerfiles (and that is not done yet) - we have this as an open issue and I would ask for a little patience.
