Webmin is an extremely useful tool for configuring your Linux machine from a web based interface. It makes management easier in some respects, such as the initial configuration of a server.
First, let’s create the local repository at this location /etc/apt/sources.list
sudo nano /etc/apt/sources.list
with the following contents:
deb http://download.webmin.com/download/repository sarge contrib
Next install the GPG key for webmin:
sudo apt-key add jcameron-key.asc
Now, we are prepared to install webmin with the YUM installer.
sudo apt update
sudo apt install webmin
If you are running firewalld, you will need to open port 10000 or the port your Webmin daemon is configured to run on.
