I've actually used apt-cacher-ng, or at least I spent two years trying. Sadly, it's a buggy pile of poop that constantly segfaults and has serious data corruption bugs. It corrupts packages. Like, all you gotta do is download a file from the internet, and it messes that up by corrupting it. All of these bugs are super well-known, written about, and documented. I never did find a good Deb package cache manager. I simply wrote a script that distributes common packages between my LAN systems as I update them in a serial matter. It works but I wish there was something better. Everything I've tried is either sub-Alpha bugware and incomprehensibly complicated.
