I'm also seeing this problem. Generic edgy, update-manager to feisty ran fine, reboot, update-manager gives this error. apt-get update/dist- upgrade confirms system is up to date for feisty. do-release-upgrade fails with just an 'aborting' message after telling me which packages may not be supported in gutsy - didn't see any other errors.
