How To Install Webmin on Ubuntu 20.04

What is Webmin?

Webmin is a powerful and adaptable web-based server management control panel for Unix-like operating systems. Webmin allows the user to configure operating system internals like users, disk quotas, services, and configuration files, as well as modify and control open-source apps like the Apache HTTP Server, PHP, and MySQL.

The requirements

1. Ubuntu 20.04 Server
2. Apache installed (Click here for the installation tutorial)
3. A valid domain name that points to your server IP.

Step 1 – Update the server package index

sudo apt update

Step 2 – Install Webmin

Open your Ubuntu source list and add the following line at the end of the file

sudo nano /etc/apt/sources.list
deb http://download.webmin.com/download/repository sarge contrib
