Step 1: Download Ubuntu Server

The first step in setting up an Ubuntu server is to download the server ISO image from the official Ubuntu website. You can choose between the LTS (Long-Term Support) version that has a five-year support window, or the latest version that has a nine-month support window. Once you have downloaded the ISO image, burn it onto a DVD or USB drive.

This will take you to the Ubuntu server installation menu, where you can select the language, keyboard layout, and other installation options. Follow the prompts to complete the installation.

Step 3: Configure Network Settings

After installation, you will need to configure your network settings, including IP address, netmask, gateway, and DNS. You can do this by editing the /etc/network/interfaces file or by using the Network Manager utility. Make sure you have a stable connection and that your network settings are correct before moving on to the next step.

Step 4: Update and Upgrade Packages

Before installing any packages or software on your Ubuntu server, it is important to update and upgrade the existing packages. This ensures that you have the latest security patches and bug fixes. You can do this using the following commands:
