Help Endless OS isnt working properly, Chrome, App center not working

[dela]

Endless OS using few years and all was working fine till now
Google Chrome won’t allow me to size up window when watching movies, not even YouTube. I tried to uninstall it and install it again. Won’t open pages from mail or Facebook.
Firefox won’t open any video because plugins arent working, Opera won’t install because it’s too dangerous for my PC.
I tried to install apps form app center and it will not install them at all, or when it does i cannot acces them.
Is there any possibility to check through terminal for viruses, I tried to install ClamAV but PC won’t let me install anything at all.
I tried to do update checks too, still the same, seem to be not reacting to anything

Hi!

You have an old Endless OS version… Please update by following these instructions:

Or by going to Terminal and entering the command:

sudo ostree admin upgrade
