兄弟们，我安装了好几次，终于安装上了，每一次的代码和初始化的失败的解决方法在下方，拿走不谢[tv_笑哭]
第一个：sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
第二个：sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
第三个：
sudo apt update
sudo apt install ros-melodic-desktop-full
第四个：
sudo rosdep init
rosdep update
如果失败：#打开hosts文件
sudo gedit /etc/hosts
#在文件末尾添加
151.101.84.133 raw.githubusercontent.com
#保存后退出再尝试

第五个：
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
source ~/.bashrc
The last one:
sudo apt install python-rosinstall python-rosinstall-generator python-wstool build-essential
bashrc
The last one:
sudo apt install python-rosinstall python-rosinstall-generator python-wstool build-essential
