Hello Matthew Paul Thomas. Thanks for your answer. If I turn off automatic installation of security updates, I will be notified immediatly of security updates, and other updates will be notified at the same time (default behaviour of update manager). I don't know if it's possible to turn off notification of security updates, do you know ?
But this logic bug seems to have been already identified in this bug report in 2009 ;) Comment #4 by Michael Vogt : https://bugs.launchpad.net/ubuntu/+source /update-notifier/+bug/356152/comments/4 "This maybe a usability bug. update-notiifer just checks when the last apt/dpkg action was performed and calcualtes the 7 days based on that. But from a user perspective installing a new software and installing a update is something different so it may not be clear why update-manager does not appear in this situation." Comment #5 by you : https://bugs.launchpad.net/ubuntu/+source/update- notifier/+bug/356152/comments/5 "Since Add/Remove is currently incapable of installing updates, and therefore using Add/Remove doesn't mean you've decided to defer updates, it would be nice to exclude use of Add/Remove from resetting the 7-day timer." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/356152 Title: update-manager doesn't show updates, even after 1 week To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/356152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
