apt-rec-deps

Manually download apt dependencies, recursively.

I sometimes need to inject packages into Debian docker images that don't have an internet connection. Here is how I gather all the packages and their dependencies:

Usage

1. Look at your system's apt package source list:

   cat /etc/apt/sources.list
   

   You'll see something like deb http://deb.debian.org/debian/ stretch main. Put the URL piece (http://deb.debian.org/debian/) into your web browser and navigate to your architecture's URL... something like:

   http://deb.debian.org/debian/dists/stretch/main/binary-amd64/
   

2. Download the Package list:

   wget 'http://deb.debian.org/debian/dists/stretch/main/binary-amd64/Packages.gz'
   zcat Packages.gz >Packages
   

3. Get a recursive list of packages URLs:

   PACKAGE=smbclient    # Set this to your desired package
   SRC_URL='http://deb.debian.org/debian/' ./rec-deps $PACKAGE >pkg_urls
   

4. Download all the packages:

   mkdir debs
   ( cd debs && wget -i ../pkg_urls )
   

5. Create a bundle:

   tar czf ${PACKAGE}_debs.tar.gz debs/
   

6. Copy the bundle to your target system.

7. Install
