Well, it was an update-manager update. I'm not sure why the user triggered one, but probably a high-level graphical tool should not allow that. For APT, it does not make sense to prevent people from upgrading itself. That said, livecd tools could create a pre-install hook that fails with "This is a live system, it does not support upgrades"?
