Ubuntu20.04 rosdep 失败解决方法

参考文章http://www.autolabor.com.cn/book/ROSTutorials/chapter1/12-roskai-fa-gong-ju-an-zhuang/124-an-zhuang-ros.html

sudo gedit ./rosdistro/__init__.py
sudo gedit ./rosdep2/gbpdistro_support.py
sudo gedit ./rosdep2/sources_list.py
sudo gedit ./rosdep2/rep3.py

全部替换文件中的 raw.githubusercontent.com/ros/rosdistro/master 为 gitee.com/zhao-xuzuo/rosdistro/raw/master

删除20-default.list文件，再init

sudo rosdep init
rosdep update
