In this article, we will learn – How we can install Webmin on Ubuntu 16.04. Webmin is a web-based control panel with dashboards for any Linux server machines, which allows you to control your server with a simple interface, where we can change the settings of common application packages with simple clicks. Webmin can also be used to add new users accounts and update the packages on the server from the Webmin dashboard itself.

Pre-requisites

  • Ubuntu 16.04 machine with a non-root user with Sudo permissions.
  • Apache, PHP, and MySQL Installed on the Ubuntu 16.04 machine.

Installing Webmin on Ubuntu 16.04

Assuming that we have all the pre-requisites, First, we need to add the Webmin official repository to the sources.list so that we can get the updates and install the Webmin using the package manager.

$ sudo vi /etc/apt/sources.list

Once we open the file we needed to add the following lines to the bottom of the files.

deb http://download.webmin.com/download/repository sarge contrib

# deb-src http://security.ubuntu.com/ubuntu xenial-security universe
deb http://security.ubuntu.com/ubuntu xenial-security multiverse
