  Upgrade to 12.04 Failed

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

Bug description:
  I run upgrade after installing all recommended updates from update
  manager, and I got dialog:

  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.
