I have a couple of debian boxes in very remote areas that are connected back to

Normally, I'd suggest looking into running a private mirror and
rsyncing it, but with only one machine at each location, that's
overkill.
I think you may want to look into apt-zip: This will decouple the
download from apt, allowing you to get the data xferred by whatever
method works (rsync?), and picking up the xferred file on the remote
location with apt...
Unfortunately, apt-zip has been discontinued - last appears in wheezy,
but it may still work or be made to work? It seems aimed at your
exact use case...
Failing that I can imagine other (hand-crafted) solutions with these
components:
- make sure /etc/sources.list (and /etc/sources.list.d) are identical
- rsync /var/lib/apt/* across
- on the remote end: run:
apt-get upgrade --print-uris # or similar
- grab the URLs
- download the *.debs and rsync them into /var/cache/apt/archives/
- on the remote end:
apt-get upgrade
This is entirely off the top of my head, but with a bit more thought
and scripting, it _should_ work...
Hope this helps
