[Bug 913724] [NEW] unable to upgrade to 12.04

[Svivi]

Public bug reported:

Hi, I tried to upgrade to 12.04 from 10.04, but it failed.

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
