I want to write a bash script that will run through my /var/cache/apt/archives directory and determine which ones are obsolete (either not the latest release, or no longer available at all from the standard Debian package repository). How can I tell which packages are obsolete?
The idea here is that I want to provide a Home for Lost Packages on my web server, for the benefit of people who are trying to get gnucash or other dependency-starved packages running. But I don't want to just make /var/cache/apt/archives visible to the world; I only want to offer packages that aren't available in the package repository, so that people will only use my limited bandwidth when it's necessary.
