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: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libglut3-dev
I changed the sources.list file, but it remains the same. How can I install this package?
