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?

Hello Ale,

I got "roscore: command not found" error

Did you source it? source /opt/ros/<Version-of-ros>/setup.bash

Then after go to your workspace by the cd <workspace-name> command.

then build your workspace by catkin_make

Again source your local work-space by source devel/setup.bash
