Let's say I have at home 3 computers running Debian testing. They mostly have the same configuration and most of the packages installed are identical.
Every time I update/upgrade the Debian packages, they are downloaded from the Internet.
Is there a way to pre-fetch the Debian packages from the Internet and have a local, up-to-date Debian repository containing only the packages I have installed that have an available update?
So, typically, if I have vim installed and an update is released, my server will go and fetch the .deb locally and I could upgrade all my machines from the LAN. If I want to install emacs, then the local repository will not have it and it will be downloaded from the Internet.
One could call it a local apt caching system, like Squid does http caching.
Thanks!

It seems that you are look for
apt-cacher
. To install it, just type:You can then configure
apt-get
to use it as proxy by creating a file/etc/apt/apt.conf.d/01proxy
with content:To be honest, I am using this configuration on ubuntu, but it should be similar on debian. This way all package downloads will be requested from
apt-cacher
on server "cacher_ip". If it exists, it will be fetched locally. Otherwise, it will be downloaded via the cacher.
