first of all you can search the forum there are already answears to your question :

here is one of them :

sudo echo 'Acquire::http::Proxy "http://yourproxy.com:port";' > /etc/apt/apt.conf.d/proxy
if its not working put the ip adress and not the name of the proxy
you can also use'it like this :

http://]login:password@yourproxy.com:port

these are topics i found with the serach button...
