现在用apt添加带ROS 2 GPG关键字

sudo apt update && sudo apt install curl gnupg lsb-release
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

将存储库添加到源列表中

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

3.安装ROS2 Iron

sudo apt update
sudo apt upgrade
sudo apt install ros-iron-desktop   ros-iron-ros-base   ros-dev-tools

三、ROS2测试

在terminal 1 运行下面的指令：

source /opt/ros/iron/setup.bash
ros2 run demo_nodes_cpp talker

在terminal 2 运行下面的指令：

source /opt/ros/iron/setup.bash
ros2 run demo_nodes_py listener

四、ROS2卸载

sudo apt remove ~nros-iron-* && sudo apt autoremove

删除ROS2库：

sudo rm /etc/apt/sources.list.d/ros2.list
sudo apt update
sudo apt autoremove
