Helps downloading packages missing from i.E. Tails distribution for placement on a USB stick for transfer to an offline system.
You specify a list of wanted packages and the script will give you a list of packages missing in the distribution, including their dependencies.
Use a local apt config:
export APT_CONFIG="apt/etc/apt/apt.conf"
apt-get update
You can now use apt-commands for querying the package database and downloading packages.
WARNING: Do not install or remove any packages - this will mess up your system (probably only if you run as root)
You need a file listing your wanted packages one package per line and a file listing the packages present in the distribution.
Example run:
./generate-downloadlist.sh wanted-packages <(cut -f 1 < tails-amd64-4.4.1.packages )
or in order to download the .debs:
./generate-downloadlist.sh wanted-packages <(cut -f 1 < tails-amd64-4.4.1.packages ) | xargs -n1 apt-get download
Currently the script will show pure virtual packages. Downloading these with apt-get download will generate an error.
Also dependencies might be missing due to this - if the virtual dependency is not satisfied on the target system.
The above download command will just skip these packages.
