[Bug 1100992] Re: Unable to run update manager

[sampo555]

Weird. No apparent errors there either. I have no idea what could be
causing this.

You could try running 'sudo apt-get dist-upgrade' as it's better at
handling dependency errors. But be careful, it can delete/install
packages so make sure nothing important gets deleted. If you see a long
list of packages being deleted or installed, you should abort the
procedure just to stay on the safe side.

Title:
  Unable to run update manager

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

Bug description:
  When I try to run update manager, I get the following message:

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  Please report this bug against the 'update-manager' package and include the following error message:
  'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

  Please note that I'm running ubuntu 10.04 and simply checking for
  udpdates, not trying to upgrade to more recent release.   When I try
  to determine the package version via  'apt-cache policy pkgname', I
  get:

  Unable to locate package pkgname
