    Why do you think it is "not recognized"? How are you trying to install "with drivers-devices"? What is the GPU? Are you connected to the internet? – Pilot6 Sep 12 '22 at 15:17

  • Try and use answers [here](https://askubuntu.com/questions/586595/restore-default-apt-repositories-in-sources-list-from-command-line) to restore your sources.list. Seems like you're aiming at resources that are no longer available (a wrong mirror, etc) – Alfabravo Sep 12 '22 at 19:25
