I know when I set it up I had to add them manually, but that was years ago. Maybe this is a new thing, or maybe your specific Ubuntu instillation was a custom fork of QB that included a bunch from the start.

(I really think it's unlikely that base QB would include them, since it would make it more obvious that they intend it to be used for piracy - something they'd want to avoid for legal reasons. Yeah, I know, but I'd rather they not get shut down.)
