Help Needed: Repackaing Propriatary launcher

Help
1

Hey There! I am really enjoying my nixos experience so far! But right now I am stuck trying to repackage a software I regularly use with FHS environments. This is the script I worked out so far:

{ lib
, stdenv
, buildFHSUserEnvBubblewrap
, fetchurl
, dpkg
, pkgs
}:

let
  amsel-suite = stdenv.mkDerivation rec {
    pname = "amsel-suite";
    version = "1.4.2";

    src = fetchurl {
      url = "https://github.com/OllamTechnologies/launcher-releases/releases/download/v${version}/amsel-suite_${version}_amd64.deb";
      hash = "sha256:d723659cdca890ee5ca15325bf3fd8d0feb346367541e1ca154704699daddc26";
    };

    nativeBuildInputs = [ dpkg ];

    unpackCmd = "dpkg -x $curSrc $TMPDIR/src || true";

    installPhase = ''
      mkdir -p $out
      cp -r $TMPDIR/src/* $out
    '';

    meta = with lib; {
      description = "Launcher for the Amsel Suite by Ollam Technologies";
      homepage = "https://ollam.ai/";
      license = licenses.unfree; # falls unklar, unfree setzen
      platforms = [ "x86_64-linux" ];
      maintainers = with maintainers; [ yourGithubHandle ];
      sourceProvenance = with sourceTypes; [ binaryNativeCode ];
    };
  };

  amsel-suite-fhs = buildFHSUserEnvBubblewrap {
    name = "amsel-suite-fhs";

    targetPkgs = pkgs: with pkgs; [
      glib
      nss
      nspr
      dbus.lib
      at-spi2-atk
      cups.lib
      gtk3
      pango
      cairo
      xorg.libX11
      xorg.libXcomposite
      xorg.libXdamage
      xorg.libXfixes
      xorg.libXrandr
      libgbm
      xorg.libxcb
      libxkbcommon
      alsa-lib
      ffmpeg
      libdrm
      xorg.libXext
      expat
      amsel-suite
    ];

    # Wrapper, der persistente Ordner anlegt
    runScript = pkgs.writeShellScript "amsel-suite-wrapper" ''
      set -euo pipefail

      PERSIST_BASE="$HOME/.local/share/amsel-suite"

      # Unterordner wie bei Steam anlegen
      for dir in home opt usr-local; do
        mkdir -p "$PERSIST_BASE/$dir"
      done

      exec amsel-suite "$@"
    '';

    extraMounts = [
      {
        source = "${builtins.getEnv "HOME"}/.local/share/amsel-suite/home";
        target = "/home/amsel";
        writable = true;
      }
      {
        source = "${builtins.getEnv "HOME"}/.local/share/amsel-suite/opt";
        target = "/opt";
        writable = true;
      }
      {
        source = "${builtins.getEnv "HOME"}/.local/share/amsel-suite/usr-local";
        target = "/usr/local";
        writable = true;
      }
    ];
  };
in
amsel-suite // {
  passthru = { fhsEnv = amsel-suite-fhs; };
}

There are multiple issues with this script, but I cannot figure out how to get it working.

First off, when unpacking the deb, tar complains about being unable to set a sticky bit on chrome-sandbox. Then, when executing the binary in the nix-store it crashes with broken pipes.

The software itself is a launcher which downloads further apps to /opt and executes them. I am wondering what I need to change in order to get a running application in the nix-store. I am relatively new to repackaging binaries, so please feel free to point out if all I have done is crap and point me towards correct ways of implementing this!

Thank you very much in advance!
