Webmin is an open-source web application for managing Linux systems. Webmin provides dashboard which is accessible to the user from a web browser. It allows to update packages, manage users and groups, configure services, and more.
This tutorial demonstrates how to install Webmin on Ubuntu 20.04.
Install Webmin
Download GPG key:
sudo wget -qO /etc/apt/trusted.gpg.d/jcameron-key.asc https://download.webmin.com/jcameron-key.asc
Add the Webmin repository:
echo "deb https://download.webmin.com/download/repository sarge contrib" | sudo tee /etc/apt/sources.list.d/webmin.list
Run the following command to update the package lists:
sudo apt update
Note: If you are receiving an error message The certificate is NOT trusted. The certificate chain uses expired certificate
, you need to install ca-certificates package and update again the package lists:
sudo apt install -y ca-certificates
sudo apt update
Install Webmin:
sudo apt install -y webmin
You can check whether Webmin service is running with command:
sudo service webmin status
We can also stop, start or restart the service:
sudo service webmin stop
sudo service webmin start
sudo service webmin restart
Testing Webmin
Open a browser and type URL address https://<IP_ADDRESS>:10000,
where <IP_ADDRESS>
is IP address of your machine. The browser will inform that certificate is not valid. By default, an untrusted self-signed SSL certificate is used by Webmin. Login to the Webmin dashboard using credentials of root or user with sudo privileges.

Thank you very much for putting this article together. It is well written and I appreciated that you used the preferred gpg method instead of the apt-key add.
