Creating  an Apt Proxy Conf File

Apt loads all configuration files under /etc/apt/apt.conf.d. We can create a configuration specifically for our proxy there, keeping it separate from all other configurations.

1. Create a new configuration file named proxy.conf.

   sudo touch /etc/apt/apt.conf.d/proxy.conf

2. Open the proxy.conf file in a text editor.

   sudo vi /etc/apt/apt.conf.d/proxy.conf

3. Add the following line to set your HTTP proxy.

   Acquire::http::Proxy "http://user:password@proxy.server:port/";

4. Add the following line to set your HTTPS proxy.

   Acquire::https::Proxy "http://user:password@proxy.server:port/";

5. Save your changes and exit the text editor.

Your proxy settings will be applied the next time your run Apt.
