Title:
  WIll not upgrade from 12.04 to 14.04

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  When trying to upgrade from 12.04 to 14.04 I get this message:

  An unresolvable problem occurred while calculating the upgrade.

  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 

  
  However none of the causes seem to apply.
