Complete reinstall possible?

Hi there,
I am facing a weird issue, with System Update: when i run it, it seems broken and close the window without me to see the steps done!

When i use ujust update, i can see that the formating is completely broken;
Is it normal?

Here is a screen of the ujust update output:

Many thanks for you advices.

Can you show what rpm-ostree status gives you?

Yes of course, here it is:

You are on the current stable image so there is no update available, new update will be today as the stable channel updates once a week.

So everything seems to be fine.

ujust update was changed a while back as we removed the ublue-update service as it was causing issues.

That error is a flatpak error, it doesn’t affect the system updates.
