Comment # 1 on bug 1225991 from Stefan Hundhammer

Let's check if there are any errors in the logs.

Please attach y2logs generated with the supplied 'save_y2logs' script. Notice
that you don't have to do the installation again for that; the logs still
contain the installation, even if there already was a log rotation.
