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 Desktop Packages, which is subscribed to cups-filters in Ubuntu. https://bugs.launchpad.net/bugs/1857815 Title: cups-browsed assert failure: corrupted double-linked list Status in cups-filters package in Ubuntu: Incomplete Bug description: Same bug on Focal ProblemType: Crash DistroRelease: Ubuntu 20.04 Package: cups-browsed 1.26.0-1 ProcVersionSignature: Ubuntu 5.4.0-9.12-generic 5.4.3 Uname: Linux 5.4.0-9-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu15 Architecture: amd64 AssertionMessage: corrupted double-linked list CupsErrorLog: Date: Thu Dec 26 08:18:13 2019 ExecutablePath: /usr/sbin/cups-browsed InstallationDate: Installed on 2019-12-12 (17 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20191211) Lpstat: Error: command ['lpstat', '-v'] failed with exit code 1: lpstat: No destinations added.
