I'm trying out the new Ubuntu 16.04 Desktop and it turns out most things I didn't like about previous releases are now fixed and I'm considering using it for a personal server.
However I don't feel like redownloading a whole ISO to get the Server edition so how do I install a server/minimal edition of Ubuntu (without the GUI) from a Desktop ISO? I'm comfortable with the command line so I don't mind if your answers are about doing a manual install via the terminal.
Searching didn't reveal much and all the results are talking about the opposite (putting a GUI on Ubuntu Server), and while I know I can uninstall the GUI later on I would prefer to not install it altogether.
Thanks.
