Are you sure you have followed all steps from the installation page? Looks like it could be an issue with the key. Please re-run steps 1.2 and 1.3 from here and try again.

This has nothing to do with ROS. The hash sum mismatch is in non-ROS package, namely python3-pygments. Also, this is more an issue with apt. Maybe look at some of the answers at StackOverflow for this? Maybe this one already helps?
