To configure the proxy on terminal and be able to use apt-get just do this :
sudo gedit /etc/bash.bashrc
add this line with your “proxy_ip” and “port_number” at the end of the file :
export http_proxy=http://"proxy_ip":"port_number"/
for sure you can do the same to export your other protocols proxies.

ENJOY!
