添加ros2仓库到本机
执行如下指令添加ros2仓库到本机：
sudo apt install software-properties-common
sudo add-apt-repository universesudo apt update && sudo apt install curl
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpgecho "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

sudo apt update
sudo apt upgradesudo apt install ros-galactic-desktopsudo apt install ros-galactic-ros-basesudo apt install ros-dev-tools
其中 ros-galactic-desktop 是完全体，包含ROS, RViz, demos, tutorials.
