I’m not sure how it is a Docker issue. I don’t even see the official Docker reository on the screenshot (although it is hard to see anything on it on my screen) and you have problems with APT repositories not related to Docker.
This is how you can install Docker
Thank you for the feedback.! I’ll make sure to use the </> button share codes and error messages from now on. Issue is solved
