SUMMARY

After a recent Neon 5.27 package update (maybe a month or so ago) Discover started to throw up a dialog telling me "The PackageKit daemon has crashed" (cf. attached screenshot).

This was reported to Discover a few times already but always closed as "please tell your Distro". Well, Neon is my distro, here you go. I actually doubt that this is a distro related issue since 
(a) it was reported for various distros (including Neon)
(b) it started happening only after some KDE Neon package update (there might have been a PackageKit update involved though)

STEPS TO REPRODUCE
This is the way it happens to me:
1. Be notified about updates
2. Open Discover
3. Deselect the Neon packages, keep only the Flatpak updates
4. Press Apply or whatever that button is labeled with
5. A dialog will pop up telling you PackageKit has crashed
6. The Flatpak updates will actually suceed. At least it looks like that.

OBSERVED RESULT
A dialog "The PackageKit daemon has crashed" pops up

EXPECTED RESULT
No such dialog

Comment 4 Malte S. Stretz 2023-11-01 08:32:02 UTC

It looks like this is a PackageKit bug indeed. Here is the Debian bug which resulted in this upstream fix which should then be backported for Neon (or maybe Discover should work around it):

* https://github.com/PackageKit/PackageKit/issues/656

Comment 5 Malte S. Stretz 2023-11-01 09:09:40 UTC

I can reproduce this reliably by downgrading the zoom flatpak and updating it again.

Comment 6 Dimitri 2023-11-29 11:57:36 UTC

I can confirm that I really often have this issue since quite a time. I don't like updating everything at the same time and most of my software are Flatpacks. (I'm also on KDE neon 5.27.9 and update through Discover.)

Comment 7 Carlos De Maine 2025-09-20 09:36:11 UTC

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
