Public bug reported: Since Xenial it seems that update-manager is not presented to users as often as it should.
One possible reason is that update-notifier is trying to be too smart about when it should open the updater and reset the counter when the dpkg/apt logs timestamps change. The logic behind that was to try to not bother command line users and don't present them the graphical UI if they are doing their update using apt directly. That's not very obvious how it's working though and not playing well with unattended-upgrades (security updates get installed in background, the system thinks it's users doing their updates manually and is never prompting as a result). The suggested fix is to just drop that smart behaviour and prompt users after the configured delay. Command line users who don't like that can just change the setting to "never" ** Affects: update-notifier (Ubuntu) Importance: High Status: New ** Changed in: update-notifier (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1702724 Title: Doesn't auto open update-manager as it should To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1702724/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
