Does the machine power off correctly if you close all your applications,
and then do
sync; sudo poweroff -f
This will directly tell the kernel to power off, without any userspace
action in between. Hence the closing of applications and "sync" to write
any outstanding data to the disk. You will also get an fsck on the next
If that still does not power off the machine, this is a kernel problem
(which I suspect as you get to the "powering off" line).

Yet another system hangs at shutdown (16.04)
Status in systemd package in Ubuntu:
Yet another of the annoying "system hangs at shutdown" bug reports. A
fresh complete install of 16.04. Just like the others, gets down to:
Reached target shutdown
then stops. I've tried all the workarounds discussed, including
swapoff -a, before shutdown attempt, etc. No joy. Have to hold power
switch for hard shutdown very time.
One observation of possible value. I also very recently installed
16.04 server on two other identical boxes. Neither of them exhibit
this problem and both shut down cleanly. Only this system, which is a
16.04 desktop version -- again on an identical box -- is having this
Frankly, it's stuff like this that makes my efforts to move ordinary
consumers over to Linux very difficult!
