My installation of Ubuntu 11.04 is complete, but I can’t update it nor can I install new applications or any other thing because I live in a university, which has a proxy server. We have to use the proxy address to access the internet in the university wireless network.
I have tried this
But there is no success yet. I can neither update the installation, nor install the restricted codecs/extras or new applications. :(
I am on a HP Probook 4321s and running this Ubuntu 11.04 (64-bits) alongside another Windows 7 Professional installation (32-bit) installation.
