【2021年8月】解决 rosdep update超时问题

修改两个文件即可快速解决超时问题

1、 修改/etc/ros/rosdep/sources.list.d/20-default.list

• 执行sudo gedit /etc/ros/rosdep/sources.list.d/20-default.list
• 在每个链接前加上https://ghproxy.com/

修改前的文件内容

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

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

修改后的文件内容

# os-specific listings first
yaml https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

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

2、 修改/usr/lib/python3/dist-packages/rosdistro/__init__.py

如果地址不存在可以尝试 /usr/lib/python2.7/dist-packages/rosdistro/init.py

• 执行sudo gedit /usr/lib/python3/dist-packages/rosdistro/__init__.py
• 修改文件第68行内容

修改前

DEFAULT_INDEX_URL = 'https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml'

修改后

DEFAULT_INDEX_URL = 'https://ghproxy.com/https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml'

再次执行rosdep update就可以啦
