Kubuntu 11.10 beta 2: Error upgrading using muon

[Dimitris Kardarakos]

After having unsuccessfully tried to perform a complete system upgrade using muon in Kubuntu 11.10 beta 1 (https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/855793) I tried the same in beta 2.

After installing I clicked on the system notification icon and started upgrade using muon update manager.

The process is stuck in 'Preparing kde-window-manager'.

In the section below find the last lines of each log file:

Ditto here -- same exact hang in the same exact spot.

(In my experience, Muon has not been very reliable for dist-upgrading.)

dpkg is hanging at this point.
