Comment 20 for bug 1817559

Ubuntu’s update prompt is a notification in the ordinary English sense of the word. <https://wiki.ubuntu.com/NotificationDesignGuidelines#Normal_window> So I guess the dconf keys predate update-notifier’s change from using FDo notifications to launching update-manager, but I don’t think that requires their name or description to be changed. (It is perverse, though, to have a boolean setting whose name starts with “no-”.)

I think the bug here is that setting “Automatically check for updates:” to “Never” has caused “When there are security updates:” to become blank+disabled, suggesting that there will be no prompts when really there will be. This doesn’t happen in 14.04, so I guess someone changed it when they realized the current menu options are only relevant to automatic checks. But besides the case where updates became known before you switched to “Never”, there’s a much more likely case where security updates might be known without automatic checks: if you did a manual check but then didn’t install them.

So, I guess the menu should instead contain options for when to remind you about known security updates that aren’t installed yet, no matter how that happened. Anyone who’s seen a billboard or digital sign defaced by a giant Windows update prompt might think “Never” should be one of the options, but I’ll defer to Steve that it shouldn’t be. (I guess we’d say that kind of thing should use Ubuntu Core instead.)
