Title:
  upgrade to 11.04 fails

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

Bug description:
  Trying to run the Distribution upgrade from 10.10 to 11.04 (attached
  log files)

  I've removed all PPA's and uninstalled all programs associated
  I've also ran "computer Janitor" to remove any non-official programs
  Removed Nvidia proprietary driver

  I keep getting the following error:

  Could not determine the upgrade

  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

  If none of this applies, then please report this bug against the
  'update-manager' package and include the files in /var/log/dist-
  upgrade/ in the bug report
