rosdep initialization error

Question

I have installed Ubuntu 12.10 a day back. And I'm trying to install ROS. I have installed ros-groovy-destop-full. When I try to initialise rosdep, I get error.

sudo rosdep init

ERROR: cannot download default sources list from: ... Website may be down.

But when I copy the address and paste into web browser, the links works. I am running behind proxy (with username/password), so it may be problem of proxy. But I have put proxy details in /etc/apt/apt.conf and apt-get is working fine behind proxy. How do I resolve this issue?

$ sudo rosdep init

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

As of today, it seems to work with proxies just fine. The key hint is that you need to use sudo -E rosdep init to propagate the environmental variables.

@cmansley : I get the same error even with the ' sudo -E rosdep init ' Just did a clean install of ROS Indigo, but still can't rosdep init. Same error: ERROR: cannot download default sources list from: ... Website may be down. Any other ideas?

I still get this error in 2016 (ubuntu 14.04.2 + ROS indigo). Has anyone been able to find a definitive a solution for this? Proxies didn't solved the problem for me, I still get this error when I try any "rosdep init", "sudo rosdep init" or "sudo -E rosdep init".

Answer 1

Have you tried to configure a system wide proxy in /etc/environment? Add something similar to this to /etc/environment

http_proxy=http://[user:password@]proxy_server:port/
https_proxy=https://[user:password@]proxy_server:port/

I guess rosdep init directly downloads the file from the link and does not use apt to get the file. So your proxy config for apt will not be used...

Hi, I have followed your instructions ; but still the error exists... Follow the link http://answers.ros.org/question/54924/groovy-error-installation/ Which told us to TRY AGAIN ?

I opened a ticket https://github.com/ros-infrastructure/rosdep/issues/271 to add support for being behind a proxy.

Can 'rosdep init / update' be done without connecting to net?

Comment by tfoote on 2014-05-22:
They both need network resources so no they can not be done offline.

For example, if my rasp has:

• Username: pi
• Password: raspberry
• Proxy_server: 192.168.1.100
• Port: 808

I will add:

http_proxy=http://pi:[email protected]:808/
https_proxy=https://pi:[email protected]:808/

Is it correct format?

Comment by prince on 2017-04-10:
Yes. It reads ok.

Answer 2

sudo -E rosdep init

This command worked for me.

Answer 3

This wound up being the solution on one system I was using (Jetson TX1 w/ Ubuntu 16.04)

sudo c_rehash /etc/ssl/certs
