Comment 8 for bug 349336

Perhaps having a history of changes would help (with the ability to rollback/reinstall). Then users could be more confident knowing that, should things go wrong, they can always come back and click undo. This somewhat relies on the assumption that users who don't know what they are doing would stick to software from repos, which could easily be reinstalled, but if less technical users are being forced to manually install debs then that sounds like another paper cut.
