[GROOVY-12.04-ARM-VPN] ValueError: need more than 2 values to unpack

[amrivera]

I am running Ubuntu Precise 12.04 | Groovy | armvl7 through VPN

I was having issues as it was not detecting my my OS. If I manually typed lsb_release -si, it would say Ubuntu, but running the command to roslaunch a file it would say that it could not detect the OS. I then found newer os_detect.py (revision 14723) that would supposedly fix the issue. After changing to the newer revision 14723, I am now having the following error. Please advice.

root@localhost:~/ros_ws# rosdep install -y -a --os=ubuntu:precise

Thanks for the report. This is a duplicate of #51
