Title:
  can't upgrade to latest version of ubuntu using update manager

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

Bug description:
  when upgrading from version .04 to .10 with the update manager (the
  one that loads on startup and asks you if you'd like to upgrade), I
  get the following error message partway into the upgrade:

  \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
  Could not determine 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

  If none of this applies, then please report this bug using the command 'ubuntu-bug update-manager' in a terminal.
  \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

  I'm not on a pre-release version, neither am I updating to a pre-
  release version.  All of the packages I have installed (that I'm aware
  of) have come either from the ubuntu store, or the synaptic package
  manager.
