I tried to reinstall update manager: apt-get install update-manager --reinstall
but first I got a crash, reported in bug #903328, then after rebooting I get a notification (yellow/orange sun in notification area) but I can't do anything, if I select show updates, nothing happens, if I select install updates, nothing happens, If I select preferences, nothing happens. If I run as root: apt-get update apt-get upgrade apt-get dist-upgrade updates get installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/899648 Title: Update manager does not install downloaded updates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/899648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
