There is a known bug tat cups-browsed can be stuck in a busy loop, bug 2018504. Most probably it is stuck for you and so does not handle the SIGTERM to shut down.
Usually cups-browsed's shutdown removes the local print queues which cups-browsed has created and therefore we should not eliminate it by doing a SIGKILL right away. So before setting the timeout to 0 I would like you to check whether your cups-browsed is stuck and if not, do further checks to investigate whether shutdown takes too long. ** Changed in: cups (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066079 Title: cups-browsed.service should have 0s stop timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/2066079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
