I feel like it's a dead loop:the installation of catkin-python3-catkin-pkg-catkin .... how to solve the problem?

Thank you very much if you could tell me how to do it.

I believe you've run into the UpstreamPackages. The correct package name for rosbash would be: ros-noetic-rosbash, not rosbash. Same for Catkin: it's ros-noetic-catkin, not catkin.

I am also having the same problem, this didn't work. Are there any solutions rather then reinstalling?

I am a novice, the principle of the error is not clear, so I have no other solution.

@Aysusya : please post a new question if you haven't done so already. If it turns out your problem does indeed have the same cause as @ylh's, it'll be closed as a duplicate.

Please provide sufficient information in your question: which commands did you use to install rosbash? Verbatim copies of any error messages, etc.
