That's a bug. Mario Vukelic seem to take care about it.

That should not cause any problem. It just changes the way the upgrade

If you don't need the desktop packages just deinstall ubuntu-desktop
and all the packages you don't need anymore.

If the machine is a important one you may want to clone it and try
the upgrade on a spare box first.
