I had the same problem, unable to upgrade from 10.04 to 10.10 that resulted from having previously upgraded KDE. I preformed the suggested steps:
A alternative (and prefered way) to test is: $ bzr get lp:~ubuntu-core-dev/update-manager/maverick $ cd maverick/DistUpgrade $ sudo ./dist-upgrade
Upgrade completed with no issues. Thanks.
