I do not know why my new Ubuntu 16.04 64-bit cannot be shut down or restart. I have to press and hold the power button to turn off.

I did some googling but I didn't find anything to help. Here is a list of files in /var/crash:

ali@persian:~$ ls /var/crash/ -l

after update && upgrade, the problem is retain and did not solve.


Does this happen after suspend? If yes, in terminal run

$ ps aux | grep suspend

If you see a hanging suspend job, it is preventing shutdown.Kill it with

$ sudo kill -9 NNNN

(Fill in job number from ps output)

This never happened to me till 16.04, now happens often!

  • no not after suspend, after while restarting or shutting down – desatir7316 Jul 30 '16 at 18:35

Finally I used sudo shutdown -rF.

Its about 3 days that I have no problem with shutdown or restart.
