以及查找路由，Hosts里面设置。更换网络等等，就差买个vpn了。都不行。

总结: 不是方法有误，而是写的不详细：

方案如下：

1. 下载 git clone https://github.com/ros/rosdistro.git 到home路径里

2. 设置，找不到找找python2.7，这个跟python主要版本有关，灵活点

xx@xx:/usr/lib/python3/dist-packages/rosdep2$ sudo gedit rep3.py
xx@xx:/usr/lib/python3/dist-packages/rosdep2$ sudo gedit sources_list.py

xx@xx:/usr/lib/python3/dist-packages/rosdep2$ sudo gedit gbpdistro_support.py

https://raw.githubusercontent.com/ros/rosdistro/master
替换为
file:///home/bozhon/rosdistro

可以检查一下，把能社会的都设置了

3. 设置(很重要，不然老有一个东西找index-v4.yaml或者其他文件)

xx@xx:/usr/lib/python3/dist-packages/rosdistro$ sudo gedit __init__.py

https://raw.githubusercontent.com/ros/rosdistro/master
替换为
file:///home/bozhon/rosdistro

4.  如果有，则删除

xx@xx:/etc/ros/rosdep/sources.list.d$ sudo rm -rf 20-default.list

5.  sudo rosdep init

6.  进入下载的rosdistro/rosdep/sources.list.d更改  gedit 20-default.list

# os-specific listings first
yaml file:///home/xx/rosdistro/rosdep/osx-homebrew.yaml osx

# generic
yaml file:///home/xx/rosdistro/rosdep/base.yaml
yaml file:///home/xx/rosdistro/rosdep/python.yaml
yaml file:///home/xx/rosdistro/rosdep/ruby.yaml
gbpdistro file:///home/xx/rosdistro/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

 7.   成功

说明：1.    /home/xx： 是home路径，rosdistro我直接下载到home路径下。  注意路径

          2. 过程中，老有些地方指示到： https://raw.githubusercontent.com，说明没有改。

         3. 我换了两个手机热点，都不行，但是也学习到了比如使用工具查找ip

    还是感谢网络上分享的同学

我的电脑是Ubuntu20.04，使用的python3,如果没有Python3的话可能是低版本Ubuntu,请找python2.7
