nix profile install fails: libgit2 error 9 – missing blob in SimulaVR/environments@91bb377 #235
Description
Activity
What version of nix are you running?
I'm unable to duplicate this on my machine (running nix 2.28.4). I'm running NixOS though, so it's possible that has something to do with it.
Also: Simula absolutely supports the Rokid Max. We're releasing compute packs in a few weeks which are explicitly designed to be plug and play compatible with the Rokid.
Reacted by rifux 🌸 Vladimir BlinkovI just verified this on a non-NixOS. It failed with Nix 2.20.4 with a different error but succeeded with the latest stable version 2.31.4
Reacted by George SingerReacted by rifux 🌸 Vladimir BlinkovI've tested this on the official Nix 2.34.5 multi-user installation:

I wanted to see if the installation method was relevant, so I switched to Nix 2.34.6 installed via
pacman.

Here is my nix.conf just in case:
~ ❯ cat /etc/nix/nix.conf # # https://nixos.org/manual/nix/stable/#sec-conf-file # # Unix group containing the Nix build user accounts build-users-group = nixbld experimental-features = nix-command flakes trusted-users = root me ~ ❯
I was testing whether Simula works as a potential display server/compositor for Rokid Max 1st gen AR glasses (considering a purchase). Installation via the documented Nix flake command fails during evaluation.
Environment
Command
Error Output
Observed Behavior
Nix evaluation fails when attempting to fetch a file from the
environmentsinput at the pinned revision91bb3777d558e809be12bcc94f6c984487994765. The error references a specific blob ID (6f37903fa7bf58d67d2bee12454315a577f56903) that the Git fetcher cannot resolve.Expected Behavior
nix profile install github:SimulaVR/Simulashould successfully evaluate the flake, fetch all inputs (includingenvironments), and build/install thesimulapackage.Steps to Reproduce
nix profile install github:SimulaVR/Simulaon a flakes-enabled Nix installation (non-NixOS)installPhaseAdditional Context
environmentsinput is used to copy skybox assets into the Nix store duringinstallPhase.Request
Could maintainers verify whether the
environmentsrepository at revision91bb3777d558e809be12bcc94f6c984487994765contains the referenced blob forAllSkyFree_Sky_AnotherPlanet_Equirect.png? If the object is missing, updating the pinned revision or providing a local-build workaround in the README would help unblock installation attempts.
