** Description changed:

  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
