Title:
  "E:Error, pkgProblemResolver::Resolve generated breaks" during
  lucid->precise universe upgrade of amd64

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

Bug description:
  The following error occurred during lucid-precise upgrade of universe
  packages of amd64

  ERROR 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

  This could be due to broken dependency (the following is the extract
  from  apt.log)

  Investigating libcv-dev
  Package libcv-dev has broken Depends on libopencv-features2d-dev
    Considering libopencv-features2d-dev 8 as a solution to libcv-dev 2
    Holding Back libcv-dev rather than change libopencv-features2d-dev
  Done

  This occurs in an automated set up and the this is what the tests do,

  1. Create a lucid base image using ubuntu-vm-builder, for amd64, and openssh-server as an additional package
  2. Bootstrap it to the Lucid ubuntu-standard image with universe packages
  3. Upgrade it to the next lts release (precise) using do-release-upgrade

  
  The automation setup is explained in 
  https://wiki.canonical.com/UbuntuEngineering/QA/Automation/UpgradeTestingSetup
  The profile name used for this upgrade is lts-universe-amd64 (the use of the profile is explained in the above wiki) - attachment 9

  An impacted job, which also gives the flow of the test is,
  https://jenkins.qa.ubuntu.com/view/Precise/view/Upgrade%20Testing%20Dashboard/job/precise-upgrade-lucid-universe/351/ARCH=amd64,LTS=lts,PROFILE=universe,label=upgrade-test/
