Description Dimitri 2021-12-08 17:10:31 UTC

SUMMARY

After the first time I try online updates (not the offline one), Discover and SystemSettings are no longer works. (Maybe it's just a coincidence and it's not related.)
The SystemSettings was already reported (crash at each start).
For Discover, it's different. Discover starts without problems. And I can see and navigate through the app library without problems.
However, when I click on the About page, it crashes instantly.
And when I click on the Update page, the page never appears. I can see there are update with the number of updates displayed on the page button. Doing updates by discover has become impossible.
This impossible update load is extremely similar to the loading for debug packet, which also no longer works.

STEPS TO REPRODUCE
1. Make the update for 5.23.3 to 5.23.4 (not offline is perhaps also a condition)
2. Start Discover
3. Click on Updates -> nothing work
4. Click on About page -> CRASH

OBSERVED RESULT
Can't access to updates or to about page.
(Also can't access to any setting from SystemSettings, which is another bug)

EXPECTED RESULT
Discover should load updates. I should be able to see them and to update what I want.
I should be able to access the about page (If I want to see info on Discover (like its version) to help solve the update issue.)

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
There's information I'm not sure about, given everything I don't have access to.
And since I'm French I probably made translation mistakes. Sorry about that.

Cannot reproduce. Can you get a backtrace of the crash? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Also what distro are you using?

The Update page from Discover

This is how the bug from the Update Page looks like. Nothing changes after waiting an hour.
There are nothing to show for the About Page, since it crash instantly.

The backtrace (I suppose). The crash repport.

This is what I can get.
I can't install debugging packages (it seems to be a similar bug).

As I followed the bug repporter, I assumed that everything the computer could give was given automatically. But it looks like I had to download the file and add it manually.
I can't install debugging packages, there is a similar bug for the installation of it.

I'm on KDE neon. Not the developer edition.

Comment 5 Dimitri 2021-12-08 22:15:36 UTC

It's been a long time since I'm on KDE neon without making a fresh install of the OS.
I have probably many things to clean. Maybe I should make a "sudo apt-get autoremove". I'm not sure if it is safe so I have not done it.
If necessary I will do a fresh reinstall.

I've also hit this previously, this is Bug 446555. How I recovered from this:

1. $ sudo apt install qml-module-org-kde-sonnet
2. Update the system through Discover
3. $ sudo apt-mark auto qml-module-org-kde-sonnet

THANKS !!!  😄👍
Everything works now.

I think it should be put as resolved.
And I think I have to do it that way.
Done.
