ros-2-setup

Here's how I setup ROS 2 Foxy on my machine (Ubuntu 20.04)

• Get GPG key
  1. sudo apt update && sudo apt install curl gnupg2 lsb-release
  2. sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
  3. echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(source /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
• Update
  1. sudo apt update && sudo apt upgrade
• Install
  1. sudo apt install ros-foxy-desktop
• Setup environment
  1. source /opt/ros/foxy/setup.bash
  2. add above line to end of ~/.bashrc
• Verify ROS is in environment printenv | grep -i ROS
