How to install packages with apt-get on a system connected via proxy?

Abstract :

The apt-get work via proxy.

 

Introduce :

Proxy is widespread using in network. Ubuntu is base on Linux and it can use proxy too. However the apt-get is not working if u only set proxy on OS.

 

Recently, I got Ubuntu 10.04 system connected via a proxy to the internet and I found apt-get can't work. So next is the solution.

 

1. Check the file /etc/apt/apt.conf.

2. if it is not here, create it.

3. Add these contents :

 

Acquire::http::proxy "http://<proxy>:<port>/"; 

Acquire::ftp::proxy "ftp://<proxy>:<port>/";

Acquire::https::proxy "https://<proxy>:<port>/";

 

4. If ur proxy has password, u should add these :

 

Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";    

Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/"; 

Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";

 

 

5. Save the file and it will work.
