I was not able to download the software libglut3-dev
in my Ubuntu 12.04.2
I was behind a proxy. I was getting the following error.
sudo apt-get install libxi-dev libxmu-dev libglut3-dev
[sudo] password for sai:

E: Unable to locate package libglut3-dev
I changed the sources.list file, but it remains the same. How can I install this package?
