Upgrade from 7.04 to 7.10 Fails

[broadmind]

I got the following error when trying to upgrade from Feisty to Gutsy:
"The system was unable to get the prerequisites for the upgrade. The upgrade will abort now and restore the original system state.

Please report this as a bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bugreport."

The only log file that has anything in it is the main.log:

looks like a collision between 2 different packagers...

I've run into the same issue. Here is the output of my main.log (apt.log and term.log are empty):

Thank you for taking the time to report this bug and helping to make Ubuntu better. Could you try removing the medibuntu line from your '/etc/apt/sources.list' file and then try upgrading again? Thanks in advance.

Prashant, I think a couple different bugs may be happening here and in other reports... in any case, there are people complaining of your error in this bug: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/153980
