To set up a proxy server in Ubuntu, you can use the built-in Network Proxy settings or configure a proxy server manually through the terminal. Here's how to do it:

1. Using Network Proxy Settings:
- Go to System Settings > Network > Network Proxy.
- Enter the proxy server details (e.g., IP address and port number) and authentication if required.
- Click 'Apply System-Wide' to apply the proxy settings system-wide.

2. Configuring Proxy Server Manually:
- Open a terminal and edit the apt configuration file:
sudo nano /etc/apt/apt.conf
- Add the following lines to the file, replacing 'your_proxy_address' and 'your_proxy_port' with your actual proxy server details:
Acquire::http::proxy "http://your_proxy_address:your_proxy_port/";
Acquire::https::proxy "https://your_proxy_address:your_proxy_port/";
Acquire::ftp::proxy "ftp://your_proxy_address:your_proxy_port/";
- Save the file and exit the editor.
- Update the apt package lists:
sudo apt update

By setting up a proxy server in Ubuntu, you can route your network traffic through a secure and private connection, which can be beneficial for accessing restricted content or enhancing network security. Whether you choose to use the built-in Network Proxy settings or configure the proxy server manually, Ubuntu provides flexible options for proxy server setup to meet your specific requirements.
