Same problem here. Xubuntu 14.04 through 16.04. Suspend, reboot, shutdown. All fail in some or other way on all the above versions.
On 16.04: shutdown -h now Failed to start poweroff.target: Transaction is destructive. and systemctl suspend fails because a suspend process is already in progress. If I kill this process, the machine suspends immediately but is unusable after power on ( black screen or no networking etc ). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441253 Title: hanging suspend job prevents shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1441253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
