seb128, as you have found a way to reliably reproduce the bug, I want to ask you to do the following:
Run the command cupsctl --debug-logging to activate logginf by CUPS. Edit the /etc/cups/cups-browsed.conf file, making sure that it contains a line DebugLogging file with no "#" in the beginning. Stop cups-browsed with sudo systemctl stop cups-browsed Wait some minutes, click away any apport pop-up. If you get a crash now it is NOT yet covered by the debug logging. Now start cups-browsed with sudo systemctl start cups-browsed wait some minutes, run "lpstat -v" repeatedly until no more remote queues get discovered. If it did not crash yet, shut down cups-browsed with sudo systemctl stop cups-browsed Wait some minutes. If it did not crash yet, repeat this procedure until you get a crash. Now attach the following files: /etc/cups/cups-files.conf /etc/cups/cupsd.conf /etc/cups/cups-browsed.conf /var/log/cups/error_log /var/log/cups/cups-browsed_log Please attach the files one-by-one, do not compress them and do not package them together. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857815 Title: cups-browsed assert failure: corrupted double-linked list To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups-filters/+bug/1857815/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
