  New

Bug description:
  Upgrade from 10.04 to 12.04 fails at the second step (Setting new software channels)
  The following message is displayed: 

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade:
  E:Unable to correct problems, you have held broken 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.
