Title:
  Cannot upgrade to 12.04

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

Bug description:
  When trying to upgrade to 12.04, the update manager fails and gives me
  the following report:

  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 using the command
  'ubuntu-bug update-manager' in a terminal.

  
  I've checked the /var/log/dist-upgrade/apt.log file but there are a number of broken packages and I'm not sure which I need to remove. 
  Some have mentioned removing the ‘libcv-dev’ package but I don't see that listed in the apt.log
