Hello, I'm installing ros hydro on ubuntu 12.04 in beaglebone black, the processor is ARMv7, the OS type is 32-bit. After running "sudo rosdep init" successed, when i run "rosdep update", it shows error as follows:

ubuntu@ubuntu-armhf:~$ rosdep update
reading in sources list data from /etc/ros/rosdep/sources.list.d
ERROR: unable to process source []:
 <urlopen error [Errno -2] Name or service not known> 
ERROR: unable to process source []:
        <urlopen error [Errno -2] Name or service not known> 
ERROR: unable to process source []:

Query rosdistro index
Add distro "groovy"
Add distro "hydro"
Add distro "indigo"
ERROR: error loading sources list:
        <urlopen error <urlopen error [Errno -2] Name or service not known> 

And I run "which rosdep" & "rosdep --version" & "apt-cache policy python-rosdep", the result is:

ubuntu@ubuntu-armhf:~$ which rosdep
ubuntu@ubuntu-armhf:~$ rosdep --version
ubuntu@ubuntu-armhf:~$ apt-cache policy python-rosdep

The error here is Name or service not known, which suggests that you don't have a network connection, or your DNS settings are incorrect.

Are you sure your network connection is working? Try ping

He never gets a ping Google, it's blocked in China:D

It is the network issue on your end ,not ROS.Please check out your network,or change to another network.

I was getting the same error. My internet was working but I still got this timeout error. Maybe my internet was slow so tried few more times and it finally worked for me.
