I am working on a project in Ubuntu 20.04 remotely. I followed the documentation and installed ROS. Yet It shows few packages couldn't be downloaded and I have broken packages. When I ran the command roscore in my terminal, I got "roscore: command not found" error. I tried / installing roslaunch but got "unmet dependencies" error. Can you provide me the exact commands to get through these issues?
