Ubuntu – How to you change Unity’s theme from the command line

bashthemes

I've seen several methods to do this.

However, most of them are not an option to me. I can't use unity-tweak-tool because I need to run the script as root. I can't seem to find a gsettings command that works (tried several by now). All I want to do is install the theme 'Ambiance-dark-red', and then set it as the default. But I need to be able to do this as root.

Can you guys help me out? I'm currently on 14.04, but it would be great if this worked on future releases.
