How to setup and use un/authenticated proxy with apt and pip

Setting Up Un/Authenticated Proxy for APT and PIP

If you’re working in an environment that requires a proxy, setting it up for package managers like APT (Advanced Package Tool) and PIP (Python Package Installer) is essential. Here’s a step-by-step guide:

APT Configuration

Unauthenticated

1. Open or create if the APT configuration file doesn’t exist using your preferred text editor. For example:

    sudo nano /etc/apt/apt.conf
   

2. Add the following lines to specify the proxy:

    Acquire {
    HTTP::proxy "http://proxy_server:port/";
    HTTPS::proxy "http://proxy_server:port/";
    }
   

   Authenticated

   If your proxy supports authentication and requires a username/password for login, use:

Acquire {
http::Proxy "http://user:password@proxy_server:port/";
https::Proxy "http://user:password@proxy_server:port/";
    }

Note: Replace your_proxy_server and proxy_port with your actual proxy server address and port as well as user and password if authetication is needed.

Save and exit the editor and test the APT connection:

 sudo apt update

PIP Configuration

Unauthenticated

you can use the following commands in the terminal to set temporal proxy configuration:

set HTTP_PROXY=http://proxy_server:port
set HTTPS_PROXY=https://proxy_server:port

used unset to remove temporal proxy configuration.

or to make the confiuration permanent create a file pip.conf

 nano /etc/pip.conf

and add the following lines, replacing proxy_url and port with your actual proxy URL and port:

[global]
proxy = http://proxy_url:port/

Finally, Save the changes and exit the text editor.

Authenticated

You can use any of these commands for HTTP or HTTPS with your proxy details:

pip install --proxy http://username:password@proxy_server:port package_name

pip install --proxy https://username:password@proxy_server:port package_name

or Add below text at the end of ~/.bashrc or ~/.zshrc:

# PIP proxy configuration
HTTP_PROXY=http://username:password@proxyserver:port
HTTP_PROXY=https://username:password@proxyserver:port

Note: Don’t forget to export the variables after setting them, to make them available to the shell session.

Export HTTP_PROXY

Again, replace your_proxy_server and proxy_port with your actual proxy server address and port.

Test the PIP connection:

pip install package_name

Replace package_name with any package you want to install.

Now, you’ve successfully set up a proxy for both APT and PIP, allowing you to work seamlessly in environments with proxy requirements.
