No updates after upgrade?

After trying out some things which were hardly reversible I reinstalled mobian about a week ago with an image from images.mobian-project.org. Since installing, I did not get a single update although the image seems to be from may 2021.

I tried it using the software app, that always throws an error: Failed to update metadata for lvfs. After running

Code:

fwupdmgr --force refresh

in the terminal, the error isn't thrown any more and the software app tells me that everything is up to date.


I tried in the terminal running

Code:

apt update

which also tells me that everything is up to date.

Code:

apt-upgrade

gives me 0 updated, 0 new installed, 0 to remove and 0 not updated.

Why I doubt that is is correct is because before the reinstallation it felt like receiving updates  regularly.

Does anybody have a clue if I might be right? Thank you!
