The stacktrace in errors.ubuntu.com is great, it gives us some better context to this issue:
The debconf-helper failed to copy this string to the debconf socket: "10 Template type already set\n\0" The stacktrace also gives us some stale memory contents: "ered is not valid. The password used must be \nbetween 8 and 16 characters.\n\n\0" That presumably comes from the MOK enrollment when installing Nvidia drivers. I'm not familiar with the process, but I've found resources online saying that when installing the nvidia drivers on an secure-boot system debconf will prompt the user asking to configure a password. Knowing that the debconf helper in pkcon is broken on Wayland (bug 2086773), my guess would be that after failing to request a password from the user, the other side of the socket closed communication which resulted in EOF when the debconf helper tried to write some more, and thus this crash. If that's the case, fixing bug 2086773 would also fix the underlying issue which triggered this bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to packagekit in Ubuntu. https://bugs.launchpad.net/bugs/2081604 Title: pk-debconf-helper crashed with SIGSEGV in pk_client_helper_copy_stdout_cb() Status in packagekit package in Ubuntu: New Bug description: random crash after installing Ubuntu 24.10 Beta ProblemType: Crash DistroRelease: Ubuntu 24.10 Package: packagekit 1.3.0-1 ProcVersionSignature: Ubuntu 6.11.0-7.7-generic 6.11.0-rc7 Uname: Linux 6.11.0-7-generic x86_64 ApportVersion: 2.30.0-0ubuntu2 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME Date: Sat Sep 21 21:56:45 2024 ExecutablePath: /usr/libexec/pk-debconf-helper InstallationDate: Installed on 2024-09-21 (0 days ago) InstallationMedia: Ubuntu 24.10 "Oracular Oriole" - Beta amd64 (20240919) JournalErrors: sept. 21 21:56:41 hostname xdg-desktop-por[3252]: Could not find WebExtensions backend: Could not find native messaging host sept. 21 21:56:46 hostname systemd[2292]: pk-debconf-helper.service: Main process exited, code=dumped, status=11/SEGV sept. 21 21:56:46 hostname systemd[2292]: pk-debconf-helper.service: Failed with result 'core-dump'.
