Principally this kind of problem got already fixed and should not occur again with the cups-daemon 2.2.4-7 package or newer. It is possible that perhaps your /usr/sbin/cupsd file got somehow overwritten by an older version.
So please try at first the following: sudo apt install --reinstall cups-daemon Then reboot the system and observe whether this makes the problem going away. Please report back here. ** Bug watch added: github.com/apple/cups/issues #5128 https://github.com/apple/cups/issues/5128 ** Also affects: cups via https://github.com/apple/cups/issues/5128 Importance: Unknown Status: Unknown ** 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/1718717 Title: cupsd crashed with SIGSEGV in avahi_entry_group_free() To manage notifications about this bug go to: https://bugs.launchpad.net/cups/+bug/1718717/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
