I don't think there is such a thing, I have never seen something like that at least.
You could start by installing Ubuntu on a machine and start experimenting for yourself, to learn the basics (and a bit more, depending on how interested you are). There are a lot of guides for various things on the internet though, just do a Google search for what you want to know and someone has usually written about it.
Just set up some small goals (setting up a mail or web server for example) and don't give up until you accomplished them.
Another option is to take some classes/trainings in Linux system administration, there should be a whole lot of them if you look around.
