Webmin - How to install on Ubuntu 15.04

Installing Webmin
To install Webmin via apt-get you will have to add it to your repository:

sudo nano /etc/apt/sources.list

After this, your repositories list will look something like this:

Go to the end and add this to the file: deb http://download.webmin.com/download/repository sarge contrib deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib Copy the above and press Ctrl+Shift+V to paste it in the editor, then Ctrl+X to save and exit the file and then hit enter when prompted for the confirmation. After performing the above actions, you need to get the GPG key the repository is signed with. So for that type in the following commands:

cd /root wget http://www.webmin.com/jcameron-key.asc apt-key add jcameron-key.asc

After adding the GPG key you need to update the source.list:

sudo apt-get update

Now you can install Webmin by typing:

sudo apt-get install webmin

Or alternatively you can try downloading the actual .deb file:

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.750_all.deb

This will download the .deb file on to the system, then you should:

dpkg --install webmin_1.750_all.deb

This will install Webmin on your system.
