Yes, many upgrade problems are due to the presence of non-standard
packages from other repos or installed manually. The update manager
disables non-standard repos (e.g. PPAs) during the upgrade to try and
reduce this problem, but sometimes you've installed a package from a
PPA or other repo that was overriding a jaunty package, and can't be
upgraded cleanly to the karmic package.

This used to be common with things like automatix which used to result
in a broken upgrade:
