Bug Description

After that, it says that it will

"418 packages are going to be removed. 1 new package is going to be
installed."

It went through, I rebooted and after that, all plasma packages were missing. I had to reinstall the kubuntu-desktop metapackage. Other packages that I installed manually where there.

I tried this 2 times already, same result. I have a log file of the dist upgrade if it helps (16MB of logs).
