I set the following command to terminal:
sudo apt install ros-noetic-
And it gives the following error:
E: Unable to locate package ros-noetic
How can I fix it ?!
note: I have already installed ROS according to the instructions at http://wiki.ros.org/noetic/Installation/Ubuntu on ubuntu 20.04
That’s not the full package name. You should instead be running
sudo apt install ros-noetic-desktop-full
