Update search and extension search error on gui

Hello.

I get an error message every time when i try to search update packages or search extensions on gui.
I would like to ask for help to resolve this problem.
Sorry for this long comment.

yes i did but no changes.

That didn't solve my problem. I did reinstall my system, and it looks like work fine.

I guess the source of problem was the old debian kernel or the old armbian system.
