I found a case in update-manager where this might have occurred but it was quite some time ago:
$ bzr log -r 1124 ------------------------------------------------------------ revno: 1124 committer: Michael Vogt <michael.v...@ubuntu.com> branch nick: main timestamp: Wed 2008-10-15 18:55:42 +0200 message: DistUpgrade/DistUpgradeController.py: - reenable cron job on failed downloads too Walter could you attach the log files from your upgrade,? You'll find them in /var/log/dist-upgrade as they might help find another case where the cronjob's status is not returned. ** Changed in: update-notifier (Ubuntu) Status: Confirmed => Triaged ** Changed in: update-notifier (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/390319 Title: Ubuntu does not automatically check for updates, even when set to To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/390319/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
