I got annoyed and reinstalled from scratch, and I do not encounter this problem anymore. So this seems to be an error introduced only if you do a do-release-upgrade from a prior version.
However, as far as I can recall, invoking shutdown and reboot from a terminal window works fine. Why I usually did is log out and then hit the power button to shut the machine down when the login greeter is shown. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1376982 Title: Reboot and shutdown options doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1376982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
