This is a quick little article showing you how to install Webmin on Ubuntu 14.10 and 14.04 (these instructions should work with older and newer versions as well).

Installing Webmin on Ubuntu

The first thing you need to do is add the Webmin repositories to your apt list (if this fails see the note below):

sudo add-apt-repository 'deb http://download.webmin.com/download/repository sarge contrib'
sudo add-apt-repository 'deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib'

Being a diligent system administrator you have, of course, checked that the URL’s I’ve given are genuine (they are but it’s worth pointing out the risk). Now you need to get the key used for signing and add it to apt so that it will trust the packages. Once you’ve added the key you can delete the original file.

wget http://www.webmin.com/jcameron-key.asc
sudo apt-key add jcameron-key.asc
rm jcameron-key.asc

Now just run and update and install Webmin:

sudo apt-get update
sudo apt-get install webmin

Once you’ve got Webmin installed you may or may not need to modify the firewall to allow access depending on your systems current configuration. By default Webmin runs on port 10000 and so should be accessible at:

http://your_server:10000/

If you are installing Webmin onto a completely fresh install of Ubuntu Server then it is likely that the firewall isn’t switched on and so you should have no trouble getting access to Webmin. If it is switched on already you’ll need to open port 10000. How you open port 10000 varies quite widely, there are several command line tools e.g. iptables and a selection of graphical tools.

You log into Webmin using your regular username and password combination that you would use at the command prompt or graphical login. Once in you should see a menu on the left which gives you access to modify the various features currently installed on your system.

Installation Failure Note

On a completely fresh server edition install the command add-apt-repository isn’t available but you can add it with:

sudo apt-get install software-properties-common
