Webmin is a web-based interface for system administration on Unix-like systems. It allows you to manage users, disk quotas, services, configuration files, and more through a simple browser interface. This tutorial will guide you through the process of installing Webmin on Debian 12.

Webmin is a web-based interface that simplifies the administration of Unix-like systems, including Linux. It’s a powerful tool that allows system administrators to manage system tasks, such as setting up user accounts, configuring Apache servers, managing DNS, file sharing, and databases, all through an intuitive web interface.

To access your newly created instance, follow these steps:

  1. Find your Instance’s Public IP: After creating your instance, note the public IP address associated with it, which is visible in the instance list.
  2. Open SSH terminal: Use an SSH client like Terminal (for Linux/macOS) or PuTTY (for Windows).
  3. Connect via SSH: Run the following command in your terminal:
   ssh root@<your-instance-ip>

Replace <your-instance-ip> with your instance’s actual public IP.

  1. Enter your password: If prompted, input your instance’s root password. You should now be connected to your instance.

Step 2: Update System and Install Dependencies

First, update your system packages:
