Apt-proxy is designed to minimize the download amount
for .debs and sources. Here some tricks one can
use with an apt-proxy server on a laptop to update
clients that have no (or a very slow) internet connection.
Material here is 'works for me'. No guaranty that it
works for you as want or wish ;)
1) apt-get update and apt-get dist-upgrade the laptop
with the apt-proxy server as long as you have a
'fast' internet connection.
If you have a list of additional pkgs you want to
serve [see 5) and (*) at the end]
apt-get --download-only install `cat my-deb.list`
At home or friends place:
2) set min_refresh_delay to a high value like 10000h
so apt-proxy does not try to update the Packages
and Sources file. Restart apt-proxy
/etc/init.d/apt-proxy restart
3) Optional: Disable access internet of the host
running apt-proxy.
4) On the client(s): modify sources.list to use the
your apt-proxy server and run apt-get update.
5) On the client(s) start 'apt-get dist-upgrade'.
Depending on 3), only pkgs missing in apt-proxy
server are downloaded from the internet or
you get a download failure.
6) Create a list of pkgs that failed or are downloaded
in 5) and the next time update them on the
apt-proxy server as described in 1. See also (*)
below.
7) Reset min_refresh_delay to old value in apt-proxy.conf
and restart apt-proxy.
Notes:
(*) How to make sure that pkgs are in apt-proxy cache
and up to date:
On apt-proxy client(s) you can create a list of
installed pkgs with
dpkg --get-selections | awk '/\<install\>/ {print $1}' > myX-deb.list
Merging lists of several clients:
sort my1-deb.list my2-deb.list ... | uniq > my-deb.list
On the apt-proxy server preload the pkgs:
apt-get --download-only install `cat my-deb.list`
apt-get clean
