ubuntu18.04 运行rosdep init ERROR：cannot download default sources list from

安装ros-melodic命令行：

$ sudo rosdep init
$ rosdep update

报错：

ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

解决方案：

 $cd /etc/ros/rosdep/sources.list.d
 #创建文件
 $sudo gedit 20-default.list 

 

写入下面文字：

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

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

保存文件

运行：

$rosdep update

 

 完成通过！！！
