Quick script to install ROS Noetic into Ubuntu 20.04 and Ubuntu 20.04 based operating systems. Right now, it works in Pop! OS 20.04 and Ubuntu 20.04. This script will NOT work in 20.10 based distros.
chmod +x ROS-install.sh
./ROS-installROS.sh
If after running the script 'roscore' command does not work, you'll need to change the ~/.bashrc yourself. You can do this with this commands:
echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc
Note that this is only for bash shells.
