Prerequisite installation with Nix fails on my PC

[wizzardx]

With a fresh Nix package manager install on Debian Testing, after a fresh git clone of this project.

Running this command:

nix-shell nimbus.nix

Results in this output:

fatal: not a tree object
error: program 'git' failed with exit code 128
(use '--show-trace' to show detailed location information)

Next, using this command:

nix-shell --show-trace nimbus.nix

Results in this output:

fatal: not a tree object

nix-shell version is 2.0.4

Sorry for the late reply. The failure is related to network I/O issues when cloning large git repositories. We've improved the situation by relying on Github tarballs instead which should be much more reliable.

I've tested our latest code with nix 2.2.1 on macOS and Ubuntu 18.04.
