[Bug 1197040] [NEW] Cannot upgrade from 10.04 to 12.04

[dwarf]

Public bug reported:

When I try to upgrade from 10.04 to 10.04 I get following error:

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the command
'ubuntu-bug update-manager' in a terminal.

I have disabled all third party software sources (as far as I know, I
did this through the "update managers" settings), but the error
persists.
