Public bug reported: Instructions say can be caused by upgrading to or running a pre-release version (doesn't apply) or by unofficial software packages (can't say if applies). This may be a feature request rather than a bug request per se. If there may be unofficial software packages on the system, wouldn't it be useful for do-release upgrade to report something that will help pinpoint what they are, and what they create trouble for?
