Upgrade Kubuntu Lucid 10.04.02 LTS to Maverick 10.10

Today i wanted to upgrade to the latest version of kubuntu (being 10.10 Maverick Meerkat) and ran into some trouble. Normally, a quite simple

sudo do-release-upgrade --dev

should do the magic, but it just throw me the following error:

An unresolvable problem occurred while calculating the upgrade: Can not mark 'kubuntu-desktop' for upgrade.

A quick look into the log-file didn't clarify things much, but helped finding the answer to the problem:

upgrade kubuntu 10.10 Can't mark 'kubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken packages.)

To sum it up, i have installed a newer version of KDE through backports than the one which comes bundled with maverick. To solve this issure, just follow these steps:

$ bzr get lp:~ubuntu-core-dev/update-manager/maverick
$ cd maverick/DistUpgrade
$ sudo ./dist-upgrade.py
