If you have multiple machines, then there's a method I haven't seen
mentioned, which might be worth a try. It doesn't require any unusual
configuration parameters.
Install apt-cacher-ng on one of the systems, then copy all the .debs
into /var/cache/apt-cacher-ng/_import and let it place them all into
a repository. You control the package by pointing your browser at
http://localhost:3142/acng-report.html on the caching machine, and
use the cache by inserting into /etc/apt/apt.conf a line like
Acquire::http::Proxy "http://192.168.1.NNN:3142/";
depending on your network configuration.
Cheers,
David.
