I have investigated further, it would seem that it is the shutdown function in ubuntu and flavors that is the problem, because sudo poweroff in terminal work just fine.
I suggest the ones still affected by this bug, try to open terminal and type: sudo poweroff your password Just to see if it work for you, please let me know. Could one of the experts here come up with a script that do the poweroff function without having to type password? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
