Course to learn solving Linux problems

Hello everyone,

I was wondering if there is a course (like RHCSA or LPIC or whatever) where you learn how to solve the most common problems, and a few less common, but important and complicated.

If not, then there should be one, because this way the student can learn which logs to read, which configs to edit, which processes to check, etc.

I'm not sure if it has to be distro dependable or generally Linux, but either way it would be a great course.
