Fix is to assure via systemd that cups-browsed is never running without
CUPS running, especially to let cups-browsed always shut down before
CUPS.
This can be reached by adding the line
Requires=cups.service
to the [Unit] section of
/lib/systemd/system/cups-browsed.service
and then to run
I can reproduce the bug. cups-browsed hangs on shutdown when CUPS is not
running any more. One can simply do
sudo systemctl stop cups
and after some seconds
sudo systemctl stop cups-browsed
with the shutdown of cups-browsed hanging.
Problem is that during shutdown cups-browsed accesses CUPS
Yes. I experienced the 1-2 minute delay / hang that I have seen since
upgrading to 16.04.

Please attach your /etc/cups/cupsd.conf and /etc/cups/cups-browsed.conf
files and post the output of
lpstat -v
once with cups-browsed running and once with cups-browsed stopped.
Also stop cups-browsed via
sudo service cups-browsed stop
and then start it from the command line via
sudo nohup
