System Settings does not start anymore on rc channel

marlboro50

@unisuperbox
I am now in the process of making a new installation of the dev channel. I tried a number of times but failed: the installer 0.8.0 beta lost connection to my device.
Now I used 0.8.1, miracle, it worked!
Below is my system.log:

It is actually the "about icon" that crashes the application.

@marlboro50 You're a genius! Yes, I can enter system settings via battery setting from the top menu. Everything works in system settings except for the About section - it makes the app crash... Maybe something goes wrong when it tries to read / display the version of the sysyem?

kugiigi

Was there any changes in the settings app recently?
not sure if it's related but the update page gets broken on the pinephone most of the time. The app blinks until it's just black. So far I only encounter this in the update page/

@kugiigi
Not that I am aware of. I just updated to 2020-12-05 without a problem.

dobey

@marlboro50 Can you run the following in terminal and then include the resulting file here? click list > clicks.txt

Thanks.

UniSuperBox

Same to @mihael, if you still have a device with this issue.

@mihael Wow, that's quite a listing. I wrote a quick script to pull all of these from the store and install them, however I have quickly found that a lot of these are no longer available in the store.

Do you have a lot of apps installed and left over from the 15.04 days?

dobey

@mihael OK. I've downloaded and installed all the ones which still are installable from open store, and while it does make loading the Storage page quite slow, there is no crash for me in settings.

AppLee

@mihael
I edited your post.
To add a code text, you can click on the icon </>

Or you can use pastebin and post the link...

mihael

@dobey Thanks for looking into this... I appreciate it very much. Yes I have a lot of old apps that I maybe never use...

mihael

@applee Thank you very much!

dobey

@mihael OK. Can you do sudo ubports-qa install xenial_-_1612crash and see if this resolves the crash for you?

Thanks.

@dobey Wow! This fixed system settings! Now it opens the app and it can go in the About menu. Thank you very much! It updated libsystemsettings1 and ubuntu-system-settings.

Would you have a symilar fix for Open Store?

marlboro50

@dobey
I ran the code "sudo ubports-qa install xenial_-_1612crash" as you suggested to @mihael and it worked for me, at least until the next channel change or upgrade.
Thank you! Good job.

dobey

@mihael said in System Settings does not start anymore on rc channel:

Would you have a symilar fix for Open Store?

I don't know what is happening there, but it seems like it is not crashing. Anyway, let's not misdirect this thread for that.

mihael

@dobey One more thing: what was the problem and how did you fix it? Thanks again!

dobey

@mihael It was some poor memory handling in the code, which was exposed by some changes that were merged recently. So I fixed the code.

mihael

@dobey Wow! Great. How come this memory problem didn't affect everybody?
