It's all about the question

There are two doors: one has a very hungry and ferocious lion behind it, the other has the fountain of all knowledge behind it. You don’t know which door leads to what. There are two guards in front of the doors. Both guards know what is behind each door. One always tells the truth. The other always lies. But you don’t know which guard always tells the truth and which guard always lies. Your task is to find the fountain of all knowledge and avoid being eaten by the very hungry and ferocious lion, but you can ask only one question to the guards.

What should you ask, and to whom?
