Agile is a set of considerations to ponder if you think you want to operate in a manager-less environment. The supplemental 12 Principles[1] goes into a bit more detail, explaining that developers need to take on jobs like communicating with the business people and amongst themselves to supplant what a manager would normally take care of.

Scrum, on the other hand, is a "process" to manage teams. It even assigns what it calls a "Scrum Master" to act as a manager. Literally the opposite of Agile. Scrum does propose that if you follow it, it can help lead you to eventual reach a state of Agile, which seems to be the source of the association, but when have you actually ever seen that happen?
