Comment 7 for bug 1488909

It actually wasn't broken, so you're right. The reason I made this assumption is that I was also switching the login manager during this installation process, and I just guessed that something would be left in an intermediary state. While that was partially true, I was able to reboot and continue using my default ubuntu desktop (albeit with a kubuntu boot screen).

Thanks, in any case, for your answer, Gene. Your comments are spot on and I totally agree.

For me, this was basically a case of trying to give Kubuntu Desktop a quick install and then go on with my daily tasks. The installation failed (for the reason mentioned in the description of this bug), apt-get install -f was failing constantly with the same error and I felt basically stuck. I did manage to repair my distro and things are back to normal.
