ROS rosdep init 和 ROS rosdep update更新失败问题（手动添加文件解决）

1 问题

因个人Ubuntu 18.04 国内网络原因，rosdep init 和 update更新失败，找了很多办法最终手动复制文件解决。

reading in sources list data from /etc/ros/rosdep/sources.list.d
Hit file:///etc/ros/rosdep/osx-homebrew.yaml
Hit file:///etc/ros/rosdep/base.yaml
Hit file:///etc/ros/rosdep/python.yaml
Hit file:///etc/ros/rosdep/ruby.yaml
Hit file:///etc/ros/rosdep/fuerte.yaml
Query rosdistro index https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml
ERROR: error loading sources list:
	 (https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml)>

2 解决方法

2.1 ROS rosdep init 解决方法

修改hosts

# github ip
# 自己的 ip
172.17.0.1 raw.githubusercontent.com git
# raw.githubusercontent.com 最新的ip  https://www.ipaddress.com 查询
185.199.110.133 raw.githubusercontent.com
#199.232.28.133 raw.githubusercontent.com

即可解决

2.2 ROS rosdep update 解决方法

1 完成上一步，会生成一个20-default.list 文件

路径为：/etc/ros/rosdep/sources.list.d/20-default.list

# 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

下载所有的文件放在/etc/ros/rosdep/ 下面

2 修改20-default.list，改为绝对路径

# os-specific listings first
yaml file:///etc/ros/rosdep/osx-homebrew.yaml osx

# generic
yaml file:///etc/ros/rosdep/base.yaml
yaml file:///etc/ros/rosdep/python.yaml
yaml file:///etc/ros/rosdep/ruby.yaml
gbpdistro file:///etc/ros/rosdep/fuerte.yaml fuerte

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

3 下载文件index-v4.yaml，放置在/etc/ros/rosdep/ 下面

此步骤可能会出问题：Query rosdistro index https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml

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

sudo 打开/usr/lib/python2.7/dist-packages/rosdistro/init.py这个文件，按照下面的代码进行修改。

# index information
#DEFAULT_INDEX_URL = 'https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml'
DEFAULT_INDEX_URL = 'file:///etc/ros/rosdep/index-v4.yaml'

5 下载文件,带文件夹放置在/etc/ros/rosdep/ 下面

地址：https://github.com/ros/rosdistro
找到下图中的几个文件夹，拷贝到/etc/ros/rosdep/ 下面

6 重新进行 rosdep update

此时应该是会成功的（未成功就多试几次），成功的提示如下：
