"rosdep update" error in Kinetic
Hello all;
I am installing Ros Kinetic in a new machine with Ubuntu 16.04. Everything goes fine, until I try to do a "rosdep update" command. I obtain the following errors repetedly:

Can you link us to the Q&As you've already looked at? Just to avoid forum members from suggesting the same solutions.
You can use the
q#nnnnnnformat to link to questions, don't need to copy-paste the complete url.Probably start with the regular things to check:
ping github.comworks?wgetany of those URLs?Everything is ok. ping works, I can do wget, clock and date correct. In the same company network, I have installed other previous versions of ROS without problems.
this seems to suggest that there is no host part in the url passed to
urlopen. If you can, it would probably be easiest to instrument therosdepcode to get it to print whatever URL it is about to pass tourlliband see whether something is wrong there.that doesn't necessarily mean that something couldn't have changed that now prevents you from doing the same of course.
I know...I am going to try to install Kinetic in another machine just to check. How can I make rosdep to print the information you a referring to?
that might be a bit drastic. What about installing Docker on a machine (if it doesn't already have it) and then using the
ros:kineticimage see ifrosdepwants to play nice? You could even do that on your own machine.by editing the sources. I don't think there is a built-in facility for this unfortunately.
