There is something i remeber now, the video didn´t work after installing, 22.04.1, and two days ago i used this command to get it working: sudo apt remove gstreamer1.0-vaapi.
I think that since that command it isn’t working anymore.
Now i think i know why the ubuntu software center is not working anymore. I reinstalled 22.04.1 again, and for firefox to get the latest version i used: "sudo killall firefox¨ and then “sudo snap refresh” , after this command ubuntu software, the orange suitcase button didn´t work anymore.
Not the cause, i give up and went back too 20.04.4, also no snap version of firefox, which i like better.
