Use axel to get source instead curl for fetchurl

Help
1

I’m trying to start a shell with Cuda. I have following shell.nix file

{ pkgs ? import <nixpkgs> { } }:

pkgs.mkShell {
  name = "cuda-env-shell";
  buildInputs = with pkgs; [
    unzip
    # other packages
    cudatoolkit
    # other packages
    binutils
  ];
}

But this fails due to following error. I have faced this before with large files like davinci-resolve for example. For davinci-resolve, my solution was to create a new flake using axel with 10 connections and it worked nicely every single time. Right now I’m facing this issue with Cuda.

I want to get Cuda but can I retrieve the src using axel instead of curl? I tried something like following but it doesn’t seem to be valid syntax?

    cudatoolkit.overrideAttrs
    (finalAttrs: previousAttrs: {
      pname = previousAttrs.pname + "-bar";
      src = runCommandLocal "${previousAttrs.pname}.run" rec { } ''
        axel \
          --num-connections=10 \
          --verbose \
          --insecure \
          --output $out \
          "https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run"
      '';
    })

Error:
