0、更换总的软件源
sudo sh -c 'echo "deb http://mirrors.aliyun.com/ubuntu focal main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu focal-updates main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu focal-security main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu focal-proposed main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu focal-backports main multiverse restricted universe" > /etc/apt/sources.list'
1、添加ROS软件源
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
添加国内源（速度快）
中科大
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'
清华（推荐）
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'
2、添加密钥
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
3、更新软件源
sudo apt update
4、开始安装ROS
sudo apt install ros-noetic-desktop-full
耗时会很长
5、初始化rosdep
sudo apt install python3-rosdep2
先检测一下是否能访问 raw.githubusercontent.com
ping raw.githubusercontent.com
这样表示能访问，按ctrl+c可停止。
若不能访问 ，则需查询 raw.githubusercontent.com 的IP地址
用于查询IP的网址： https://ping.chinaz.com
sudo gedit /etc/hosts
在末尾添加入下语句
185.199.110.133 raw.githubusercontent.com
若有如下错误：
ERROR: default sources list file already exists: /etc/ros /rosdep/sources.list.d/20-default.listPlease delete if you wish to re-initialize
输入以下命令：
sudo rm /etc/ros/rosdep/sources.list.d/20-default.list
终于可以进行初始化
sudo rosdep init
6、更新rosdep
rosdep update
如果上述没成功请参考此链接执行手动下载

7、设置环境变量
输入以下命令：
echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc
8、 安装rosinstall
输入以下命令：
sudo apt install python-rosinstall python-rosinstall-generator python-wstool build-essential
9、 验证ROS是否安装成功
