Thank you.

The error is
2009-11-26 10:15:00,635 ERROR Exception during pm.DoInstall()
Traceback (most recent call last):
  File "/tmp/tmpyBw8KR/DistUpgradeView.py", line 182, in run

SystemError: E:Couldn't configure pre-depend mysql-server for mythtv-backend-master, probably a dependency cycle.
2009-11-26 10:15:00,638 ERROR SystemError from cache.commit(): installArchives() failed

This is a dependency cycle when dist-upgrading from mysql-server 5.0 to 5.1 . But according to bug 413789 this should have been fixed in update-manager 0.126.1
A dirty workaround if to remove mysql-server before upgrading then reinstall it after the upgrade.

There is enough informations and I'll let the developer handle it from here.

Thanks for your help to make Ubuntu better.
