This is the 2023.07.17 release but which contains packages for various distributions (Debian-like using dpkg, RHEL-like using yum/rpm, Arch Linux and Alpine (.apk)).
The packages are totally self-contained: they include all what you need to run GDB+Pwndbg after installation.
They do not rely on any dependencies and are build in (hopefully) reproducible way using Nix package manager.
Please ignore the 'source code' attached, it is fr later commit than 2023.07.17. The packages were build from the 2023.07.17 version.
