[Bug 1032490] Re: do-release-upgrade through command line fails

[Ragi Yaser Burhum]

It also failed through the GUI. After further digging around forums
/var/log/dist-upgrade/apt.log (which funny enough I just realized is
attached) I figured out that OpenCV was breaking thing. After an
uninstall of that everything went smoothly. You know, having the GUI
doing a simple grep for "Broken" in apt.log would have been extremely
helpful.

Title:
  do-release-upgrade through command line fails

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

Bug description:
  Trying to upgrade from the command line from Ubuntu 11.10 (GNU/Linux
  3.0.0-23-generic x86_64) to Ubuntu 'precise' using do-release-upgrade
  and it fails.

  I get the following message at the end:

  
  Checking package manager
  Reading package lists... Done

  Could not calculate 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 using the
  command 'ubuntu-bug update-manager' in a terminal.

  
  Since I am not upgrading to a pre-release, nor running the current pre-release nor running unofficial packages not provided by Ubuntu, I decided to report the bug.
