I've been trying to find official documentation explaining in detail the exact meaning of Apt's output codes: Hit, Get, Ign when running "apt-get update". I've had no luck, and postings on various other sites don't always seem to agree. I'm surprised that such an important thing is so hard to find official documentation on, or at least a concrete 3rd party answer. Answer's backed by proof are the next best thing to official documentation, so I've started this thread to discuss and share test results, in the hopes of establishing exactly what each of these 3 codes mean, and backing it up with supportive proof. I've been using APT long enough to know that none of these impede my ability to use the system, but it's time to dig a bit deeper. I'm not the first person to ask what these codes mean, but maybe I can be the last.
My guess, at present, would be that:
Get = Package list is downloaded.
Hit = Package list is found, but not downloaded. Why? Perhaps because it's not newer than the currently downloaded version?
Ign = Package list is ignored. Why?
