Updating system repository 

It is extremely important that update your APT repository before getting the new package:

sudo apt update

sudo apt install -y wget apt-transport-https software-properties-common
2. How To Install Webmin on Ubuntu - apt-get install wget apt-transport-https software-properties-common

sudo wget -q -O- | sudo apt-key add -

7. How To Install Webmin on Ubuntu - systemctl status webmin

To check the version of the Webmin, use the following command:

dpkg -l | grep webmin
8. How To Install Webmin on Ubuntu - check Webmin installed package

It displays that we have installed version “1.974”.

Configuring Firewall

Webmin listens on port 10000, but your firewall blocks it. You must first allow port 10000 on your firewall so that you can log in to Webmin. 

sudo ufw allow 10000/tcp
9. How To Install Webmin on Ubuntu - ufw add webmin port

After that, restart the firewall to see the changes:

sudo ufw reload
10. How To Install Webmin on Ubuntu - ufw reload

To check the status of the firewall, use:

sudo ufw status
11. How To Install Webmin on Ubuntu - ufw status

Using Webmin on Ubuntu

In this section, we’ll cover the first steps at Webmin so that you can feel the taste of the ease of Linux server management.

Accessing Webmin’s UI

Once port 10000 is opened, you can use your browser and enter your server IP address or hostname to connect to it:

  • https://IP-address:10000
  • https://hostname:10000

At first login, the warning web page will appear, which tells you that the website you’re connecting to has an invalid SSL certificate. This happens because Webmin produces its SSL certificate during the installation, and your browser can not validate it.

You can install your own valid (paid) certificate later.

As for now, click on the “Advanced” tab:
