Unable to install ROS Melodic on Ubuntu 19.04
I am trying to install the most recent version of ROS on Ubuntu 19.04 Disco Dingo. However, when I go to terminal and enter the command "sudo apt install ros-melodic-desktop-full", I get an error message saying "Unable to locate package ros-melodic-desktop-full". I have precisely followed the steps on this website and I have updated all my software. Is there any way I can install ROS without having to do a full downgrade of Ubuntu?
