Title:
  "'E:Error, pkgProblemResolver::Resolve generated breaks, this may be
  caused by held packages.'

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

Bug description:
  Hello,

  I was trying to make the upgrade from 11.04 to 11.10 when prompted for
  the upgrade but I received the following error when trying to do so.

  'E:Error, pkgProblemResolver::Resolve generated breaks, this may be
  caused by held packages.'

  
  I also get the following error when I click 'Install Updates' under update manager 
  "This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time."

  "The following packages have unmet dependencies:

  ia32-libs: "

  Thanks a ton for the help :)
