1 设置国内源
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors./ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'
2 设置密钥
sudo apt-key adv --keyserver --recv-keys F42ED6FBAB17C654
3 安装rosdep
sudo apt install python-rosdep2
4 安装melodic
sudo apt-get update
sudo apt-get install ros-melodic-desktop-full
sudo apt-get install ros-melodic-rqt*
5 设置环境
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
source ~/.bashrc
6 然后初始化rosdep
sudo rosdep init
rosdep update
如果提示没有rosdep就执行
sudo apt-get install ros-melodic-desktop-full
sudo apt install rospack-tools
如果rosdep执行报错就参考下述网址

7 安装building packages and catkin tools
sudo apt-get install python-rosinstall python-rosinstall-generator python-wstool build-essential python-catkin-tools
8 测试
打开一个终端输入roscore
再打开一个终端输入rosrun turtlesim turtlesim_node
再打开一个终端输入rosrun turtlesim turtle_teleop_key
然后就可以控制小海龟移动了，至此成功。
9 采坑记录
ROS安装中报错解决 /var/cache/apt/archives/python-rospkg-modules_1.1.9-1_all.deb
参考这篇博客：/yeya24/article/details/80471726
#使用这个指令：sudo dpkg -i --force-overwrite <filename>
$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/python-rospkg-modules_1.1.9-1_all.deb
#然后：
$ sudo apt-get -f install
