Hi, I am installing Diamondback afresh on Ubuntu10.04 using repository deb packages. The steps are followed as given in wiki. By default rosinstall is not setup. I am stuck while following the steps as in http://ros.org/wiki/rosinstall . I am behind a proxy for which http_proxy and https_proxy is defined.

Following is the output on console:

Searching for rosinstall

Reading http://pypi.python.org/simple/rosinstall/

Download error: [Errno -2] Name or service not known -- Some packages may not be found!

This repeats couple of times. Is this issue related to proxy??? I do not face any problem when having a direct internet connnection.

Also installation of package ros-diamondback-ros-release deb ver:0.1.14-s131s503298 do not help.

I had also tried using pip. Following is the output of pip log.
