shutdown delay because of cups

[Cliff Carson]

Both my desktop and laptop running 20.10 have a 90 second delay shutting down (power off or restart). Getting message;

A stop job is Running for Make remote CUPS printers available locally

After 90 seconds the shutdown continues to completion.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[shemgp (shemgp)]

Quick fix:

sudo sed -i '/ExecStart=/a ExecStop=/bin/systemctl stop cups.service' /lib/systemd/system/cups-browsed.service

Got the idea from previous 16.04 bug with cups-browsed.service.

[shemgp (shemgp)]

Work around (the previous one doesn't work):

sudo sed -i '/ExecStart=/a ExecStop=/bin/bash -c "ps -AfH | grep cups-browsed | awk '\''{print $2}'\'' | xargs kill -s 9"' /lib/systemd/system/cups-browsed.service
sudo systemctl daemon-reload
sudo systemctl restart cups-browsed.service

[Till Kamppeter (till-kamppeter)]

The shutdown problem of cups-browsed was already identified and is fixed in the GitHub repository of cups-filters. This fix will be included in cups-filters 1.28.2 which will get released soon.

[Till Kamppeter (till-kamppeter)]

I have released cups-filters 1.28.2 upstream yesterday:

https://openprinting.github.io/cups-filters-1.28.2-released/

It also got already uploaded into Debian and I will sync it to Ubuntu as soon as it got processed at Debian.

[Till Kamppeter (till-kamppeter)]

cups-filters 1.28.2 uploaded to Ubuntu.

[shemgp (shemgp)]

I can confirm that it's fixed with: cups-filters 1.28.2-1

Thank you.

[Till Kamppeter (till-kamppeter)]

Thank you very much. So I am closing here now.
