ADDITIONAL INFORMATION

Update: I also couldn’t update with pkcon. Pkcon seemed to hang and “sit and spin” for about a half-hour at the “Running” phase of the update. I updated my flatpaks on the command line, and then I tried pkcon again, and pkcon still seemed stuck. So I tried Discover again, and it worked. It seemed to install the updates unusually quickly.

That's weird, never seen that before!

Can you attach a backtrace of the crash? See the note in the SUMMARY section. :)

Comment 3 Eric R 2021-11-26 14:39:40 UTC

I tried to generate one at the time with the Crash Report tool, but it didn't. The crash hasn't happened for about a week, and I have done a couple of successful updates since then, including one just now. 

I read the link about backtraces, and I made sure I have GDM and coredumctl installed. coredumpctl didn't get me anything just now.

So, if it happens again, I'll try to get you a backtrace or a coredump so you have something to work with. Meanwhile, it seems that I can work around this on the command line with `pkcon update`, `flatpak update`, and `snap refresh`.

Recently, I have seen at least a couple other people asking on Reddit about this same behavior, I think in r/kde or r/kdeneon IIRC. I don't think any of them had any more info than I do, though.

Thanks!

OK, thanks! Do let us know if you manage to get a backtrace of the crash.
