Prerequisites

You must be running Ubuntu 20.04.

Setup your sources.list

Setup your computer to accept software from packages.ros.org.

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

Set up your keys

curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

Installation

Update the package index and then install the ros-noetic-dektop-full package, which installs all ROS packages plus Gazebo.

sudo apt update
sudo apt install -y ros-noetic-desktop-full

Environment Setup

You must source this script in every terminal you use ROS in.

source /opt/ros/noetic/setup.bash

It can be convenient to automatically source this script every time a new shell is launched. The following command will do that for you.

echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

Setup Workspace

Install build tools.

sudo apt update
sudo apt install -y python3-catkin-tools

Create a catkin workspace and build it.

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/
catkin build

Sourcing the Workspace

Source the workspace.

echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc
