ubuntu18.04安装ros遇到的问题

1.执行curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

gdp:找不到有效的OpenPGP数据

主要是因为raw.githubusercontent.com是外网 无法访问

wget http://packages.ros.org/ros.key
sudo apt-key add ros.key

2.sudo rosdep init超时问题

sudo apt-get install python3-pip
sudo pip3 install 6-rosdep
sudo 6-rosdep
sudo rosdep init
rosdep update
