zstd decompression support for Debian

This is a patched dpkg package for debian

• This adds support for zstd decompression of ubuntu deb packages.
• Why? If you would like to be able to install deb packages from a ubuntu repository in debian.

Installation

• Download the deb packages and install:

git clone https://github.com/tmiland/dpkg-zstd-patches.git

sudo dpkg -i ./deb-packages/dpkg_1.20.12_amd64.deb

sudo dpkg -i ./deb-packages/dpkg-repack_1.47_all.deb

dpkg-repack is downloaded from the bullseye repo with:

apt download dpkg-repack=1.47

*** Not needed if you are running bullseye ***

On bookworm it's Because of the following error:

The following packages have unmet dependencies:
 dpkg-repack : Depends: dpkg (>= 1.21.0)

Add to /etc/apt/preferences to pin the dpkg packages: *** Keeps them from being updated ***

sudo nano /etc/apt/preferences

Package: dpkg dpkg-repack
Pin: release *
Pin-Priority: -100
