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?
