I also can not connect to wi-fi network. Network is disconnected after login and nothing happens when I click on "Connect" button of plasma-nm applet. Wired network is working. I am also experiencing this. Given that kded5 hasn't been successfully rebuilt on the CI since the 28th of May, I'd be incline to believe that there's some ABI incompatibility or similar that leads to the crash. It's not crashing in kded though. It's crashing peculiarly non-neon paths again. Also I think this may be an actual bug in the new kdecoration, from the memory addresses involved it looks an awful lot like it falls over a null pointer. Hard to tell where because of the peculiar paths and the lack of debug symbols caused by them. Please get the output of all these commands: mount | grep lib stat /lib stat /lib/x86_64-linux-gnu stat /lib/x86_64-linux-gnu/libkdecorations2.so.5 stat /lib/x86_64-linux-gnu/libkdecorations2.so.5.22.80 sha1sum /lib/x86_64-linux-gnu/libkdecorations2.so.5.22.80 stat /usr/lib stat /usr/lib/x86_64-linux-gnu stat /usr/lib/x86_64-linux-gnu/libkdecorations2.so.5 stat /usr/lib/x86_64-linux-gnu/libkdecorations2.so.5.22.80 sha1sum /usr/lib/x86_64-linux-gnu/libkdecorations2.so.5.22.80 grep kdecoration /proc/`pidof kded5`/maps grep kdecoration /proc/`pidof plasmashell`/maps apt policy libkdecorations2-5v5 apt policy libkdecorations2-5v5-dbgsym apt policy usrmerge apt-mark showhold apt list --upgradable pkcon repo-list myuser@neon-laptop:~$ mount | grep lib

Here's my debug output: https://invent.kde.org/-/snippets/1684. Thanks I see what's wrong with the paths now, I don't really understand gdb's behavior though, anyway will have a think and see where to best solve this. I also think I know what's wrong with this crash. I will stage a fix momentarily. As an addendum: when your system gets eaten by crash loops you can run `systemctl mask --runtime coredump-processor@` to stop it from processing crashes ;) Probably should detect that somehow automatically I can confirm that after updating my system completely the issue is gone. :) Thanks. My system is usable again! Thank you very much Harald. :) |
