Crash occurring while adding and clicking the widget
Failed to load vulkan: Cannot load library vulkan: vulkan: cannot open shared object file: No such file or directory initInstance: No Vulkan library available Failed to create platform Vulkan instance Unable to detect GPU vendor. LaunchProcess: failed to execvp: /usr/lib/qt6/libexec/QtWebEngineProcess LaunchProcess: failed to execvp: /usr/lib/qt6/libexec/QtWebEngineProcess [5984:5984:0330/133641.706141:FATAL:zygote_host_impl_linux.cc(201)] Check failed: . : No such file or directory (2) Trace/breakpoint trap (core dumped) This is your system being misconfigured. Why is it trying to use Vulkan? That's experimental and not formally supported. I would recommend that you undo whatever you did to configure the system to use Vulkan. Hopefully that will resolve the issue. I'm not able to reproduce this on git-master, but I am able to reproduce on a stock KDE Neon Testing VM After plasmashell crashed, it crashed in a loop, making the desktop unusable I had to stop the process and remove the dictionary widget from ~/.config/plasma-org.kde.plasma.desktop-appletsrc and then restart plasmashell I tried to get a better backtrace. After installing additional debug packages, running gdb on the coredump results in being killed by oomkiller I couldn't reproduce with OpenSuse Tumbleweed or Fedora 41. This may be a packaging issue in Neon. The most complete backtrace I could get without oom

Hopefully that > will resolve the issue. The original report was produced on a VMware virtual machine with open-vm-tools-desktop installed. This was a clean installation; I did not manually enable Vulkan or modify any other graphics settings. I just installed the system again in the VM, but this time I did not install open-vm-tools-desktop. I am still able to reproduce this issue, and the same Vulkan error appears. The process was straightforward: Install KDE Neon -> reboot -> enter account password -> add dictionary widget -> crash. I can also reproduce this issue on: Kubuntu 24.10 KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.6.2 However, I am unable to reproduce it on Fedora, where the widget works normally: Fedora 41 KDE Plasma Version: 6.2.1 KDE Frameworks Version: 6.7.0 Qt Version: 6.7.2 (In reply to Rik Mills from comment #7) > Could be as a result of > https://discourse.ubuntu.com/t/spec-unprivileged-user-namespace-restrictions- > via-apparmor-in-ubuntu-23-10/37626 can confirm this is an apparmor profile issue editing /etc/apparmor.d/plasmashell to `/usr/lib/qt[5,6]/libexec/QtWebEngineProcess cx -> &plasmashell//QtWebEngineProcess,` fixes dict and browser applets this fix and others is already in the released apparmor 4.0.2 tarball but noble unfortunately only has 4.0.1 which doesn't. both plucky and oracular have 4.1.0~beta, so the question is whether to put apparmor in noble-backports or croos fingers and hope it's backported into noble by ubuntu promptly. have added an apparmor local profile in the plasma-workspace package which allows the new qt6 path for qtwebengineprocess to execute. also filed an m.r. upstream to have this shipped in the default profile - https://gitlab.com/apparmor/apparmor/-/merge_requests/1633 *** Bug 509216 has been marked as a duplicate of this bug. *** *** Bug 496717 has been marked as a duplicate of this bug. *** |
