In this tutorial, we will show you how to install Usermin on Ubuntu 20.04 LTS. For those of you who didn’t know, Usermin is a web-based interface mainly for webmail designed for non-root users to perform routine tasks including, reading mail, changing passwords, setting up databases, and a web-based SSH terminal. It’s a stripped-down version of Webmin that’s intended for regular users without always system administrators.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS.

  • SSH access to the server (or just open Terminal if you’re on a desktop).
