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

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

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

  The impacted job is
  https://jenkins.qa.ubuntu.com/view/Precise/view/Upgrade%20Testing%20Dashboard/job/precise-upgrade-lucid-universe/ARCH=amd64,LTS=lts,PROFILE=universe,label=upgrade-test/338/

  The logs are attached
