Okay got it. This is the exact reproducer you just need to push it somewhere and then clone the remote. See https://github.com/mohe2015/nixpkgs-137998-reproducer git clone https://github.com/mohe2015/nixpkgs-137998-reproducer.git
cd nixpkgs-137998-reproducer/
nix build .#helloreproduces. Edit: I won't work on a fix for now but now it should be easy to reproduce. |

Can confirm that rm flake.lock # important
nix run github:NixOS/nixpkgs/7cf9185aaeb95f79cfe9cae8689433434576aaff#nixUnstable build .#helloworks but rm flake.lock # important
nix run github:NixOS/nixpkgs/release-21.05#nixUnstable build .#hellodoesn't. So it's 21c1c06#diff-b94b72b12e07bed8c4a3b4c50242499d5efb1e32797426d319574fd613bc07ae and therefore one of NixOS/nix@47e96bb...3c56f62 Current bisect status: git clone git@github.com:NixOS/nix.git

Potentially looks like duplicate of NixOS/nix#4623 |

Edit: @laikq If it's just that .tar.gz file you could probably also fetch it with nix directly and not use lfs at all. |

It seems like you sometimes need to garbage collect to reproduce btw. |
This may or may not be like the regular fetchers. If Nix already has the output with the right name and hash in the store, it doesn't need to fetch it again. This is usually a good thing, unless you are testing changes. |

I marked this as stale due to inactivity. → More info |

I have also hit this. Did you ever manage to resolve this? |

This is a problem of the nix package manager and the linked issue, not nixpkgs. |

Describe the bug
My nix flake cannot be built. The git repository of the flake uses LFS. Error message:
(here,
cvode-2.5.0.tar.gzis a file already present & downloaded in the working directory)Using
nix.package = pkgs.nixUnstable;inconfiguration.nix, wherepkgsis fromhttps://nixos.org/channels/nixos-21.05on 2021-09-15. It also doesn't work if I try to pull the flake from remote:nix build "git+ssh://git@gitlab.com…"still fails with exactly the same error message.Using
https://github.com/nixos/nixpkgs/archive/7cf9185aaeb95f79cfe9cae8689433434576aaff.tar.gz(release-21.05from 2021-09-05) aspkgs, it works again.Steps To Reproduce
I don't have a minimal working example yet, sorry :/ (I first wanted to sketch out the issue, don't have much time available right now) I guess it will happen with many git lfs repositories?
Expected behavior
Package should be built.
