When I am installing ROS Indigo following the installation guide under Ubuntu 14.04, I am stuck at the step "Initialize rosdep".
I use the sudo rosdep init command but an error occurred saying
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.
Similar problem can be found on the Internet but the strange thing is I can successfully access this link through the browser or using wget command in the terminal.
Can someone help me solve the problem?
I also notice that using req=urllib2.openurl(xxx) under python, I cannot get any response from any github link such as github dot com or xxx dot git
I am not very familiar with python but could it be a problem?
Same thing happened to me during installation and "sudo rosdep init". Tried different suggestions but the one solved my problem is simply switched my wifi to another hot-spot. Hope this helps.
