Title:
  Ubuntu upgrade from 10.04 to 10.10 fail

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

Bug description:
  I try to update from Ubuntu 10.04 to 10.10 or from 10.04 to 12.04 but
  never succeeded. I used update-manager it failled, I then used the
  following command command prompt and try to upgrade again it still
  failed,

  >sudo apt-get update && sudo apt-get upgrad
  >sudo apt-get dist-upgrade

  All the third party software in source.list are disable, I try off
  offline iso alternative cd, yet all failed

  >sudo unmount -o loop /home/adebayo/Downloads/ubuntu-10.10-alternate-i386.iso /media/cdrom
  >sudo sh /media/cdrom/cdromupgrade

  Some o the error messages are: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

  Please help out. Thanks
