In this short and straightforward article, I will explain how to install Webmin on Debian 9 and its derivatives such as Ubuntu and Linux Mint systems.

Step 1: Add Webmin Repository

1. To add and enable Webmin official repository, you need to first create a file called webmin.list under /etc/apt/sources.list.d/ directory.

$ sudo vi /etc/apt/sources.list.d/webmin.list
$ sudo nano /etc/apt/sources.list.d/webmin.list

Then add these two following lines to the file.

deb sarge contrib
deb sarge contrib

2. Next import the GPG key for the above repository as follows.

$ wget
$ sudo apt-key add jcameron-key.asc

Step 2: Install Latest Webmin Version

3. Now update the system and install Webmin like this.

$ sudo apt update
$ sudo apt install webmin

Attention: If you are using a firewall, please open port 80 and 10000 to enable access to the Webmin.

Once the installation is complete, start Webmin for the time being and enable it to auto-start at the next system boot as follows.

$ sudo systemctl start webmin
$ sudo systemctl enable webmin
$ sudo systemctl status webmin

Step 3: Access Webmin Control Panel

4. Webmin service listens on port 10000, so open a web browser and type the following URL to access Webmin.


Then provide user credentials for the system; enter your root or system admin user login password to access Webmin dashboard.

  1. When I do:

    $ sudo systemctl start webmin

    I get this error:

    Failed to start webmin.service: Unit webmin.service not found.

    Any ideas?

    • @Mex

      First ensure that you have actually installed Webmin as shown in this guide; if so, then try to go into /var/webmin directory:
      $su –
      #cd /var/webmin

      And look through these files for any errors:
      #cat miniserv.error
      #cat cat miniserv.log

      • I just tried,

        $ sudo systemctl start webmin

        again, and somehow everything seems to be working fine. No idea what happened before, I tried a few times. Anyway, all seems good now.

          Oh, may be it was a system delay in reading the unit file or some other configs. Good that it’s up and running, thanks for the feedback.
