How to use apt-get behind proxy server (Ubuntu/Debian)

If you’re using Synaptic

Open up your Synaptic package manager (usually as root), go to Settings-> Preference -> Network. Enter your proxy server details like : username:password@proxyserver.net, and put the proxy server port (usually 8080).

If you’re using command-line apt-get

Edit your /etc/bash.bashrc file as root.

Put these line at the end of your /etc/bash.bashrc file :

export http_proxy=http://username:password@proxyserver.net:port/ export ftp_proxy=http://username:password@proxyserver.netport/ 

You can omit the username:password, if your proxy server has no password.

 

The lower-case export lines with quotes worked for me:
export http_proxy=”http://username:password@proxyserver.net:port”
export ftp_proxy=”http://username:password@proxyserver.net:port”
But I appended them to the file /etc/profile instead of /etc/bash.bashrc so that it would effect synaptic from the menus (and lots of other system programs).
