Using the debug process found here https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1464917 I have determined that the cause of my 16.04 install's shutdown hang is cups-browsed. It was the only process running when I did a did a systemctl list-jobs in the VT9 shell. If I do sudo service cups-browsed stop and then shutdown, I do not get a hang. |

I have confirmed this on a virtual machine and a real system. If I disable cups-browsed from ever starting, my problem is fixed. |

[SRU justification]
When the system is shut down CUPS and cups-browsed are not shut down in a determined order, but cups-browsed needs CUPS still running to perform its shutdown, for removing the print queues it has generated and for saving information about these queues for use in the next session. With CUPS already shut down cups-browsed simply hangs and gets killed after a certain timeout. This can be fixed by defining the correct relationships in the systemd .service files and so the annoying hang can be avoided.
[Test case]
To reproduce the bug run
sudo systemctl stop cups
and after some seconds
sudo systemctl stop cups-browsed
with the shutdown of cups-browsed hanging.
On system shutdown one gets the hang, but not always as it can happen that on some shutdowns cups-browsed shuts down before cups.
After installing the fixed package, hhutting down cups requires shutting down cups-browsed before, so that the shutdown of cups triggers the shutdown of cups-browsed, making all shutdowns having the two services shut down in the right order avoiding a hang.
[Regression potential]
None. We only define a dependency between two services to make them shit down in the correct order.
