Hello folks. Today we are going to learn how install and use Webmin on Fedora 30. Webmin is a web based interface for administering Unix-like systems using any modern web browser.

Installing Webmin on Fedora 30

On Fedora 30, Webmin can be installed via the RPM package manager or directly via the Webmin YUM repos. In this guide, we will learn how to install Webmin in both ways.
