[Brecht007]

Public bug reported:

upgrade-manager -d gave the following error dialogbox when trying to upgrade from 11.10 to 12.04
____________________________________________________________________________________________
An unresolvable problem occurred while calculating the upgrade:
E:Fout, pkgProblemResolver::Resolve heeft niet-werkende pakketten veroorzaakt, dit kan zijn veroorzaakt door vastgehouden pakketten.

 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

Als niets hiervan van toepassing is, dan verzoeken wij u deze fout te rapporteren in een terminal via het commando 'ubuntu-bug update-manager'.
