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
rosbashwould be:ros-noetic-rosbash, notrosbash. Same for Catkin: it'sros-noetic-catkin, notcatkin.Thank you very much for your reply.I tried it according to what you said, but it all shows the latest version.It didn't work.
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.
