Comment 6 Andres 2020-08-07 21:19:43 UTC
I figured out how to reproduce the crash on my system if I have more than 15 updates selected at once it will crash. so i can update the whole list of pacakages by selecting 15 at a time, however they don't seem to be achtually installing and the updates will just come back when i check for updates
Comment 7 Aleix Pol 2020-08-11 00:36:33 UTC
This is super weird. I can't reproduce  and the backtrace doesn't really bring any information. Maybe you could bring the rest of the threads?

something I forgot to mention is I can no longer seem to get it to crash but it does hang when I do an update. also might be unrelated but I am unable to search for new applications/plasma addons in discover

Comment 16 Riccardo Robecchi 2020-11-15 11:18:04 UTC
It is currently fixed for me.
Comment 17 Aleix Pol 2021-03-05 15:44:57 UTC
Let's close as fixed, there's been a lot of fixes since that date and the reporters cannot reproduce anymore.
Please reopen if you get it to crash on a supported release.
