This is a temporary fix I found while we wait for this to be resolved:

Add nixpkgs-staging to your inputs: nixpkgs-staging.url = "github:nixos/nixpkgs/staging";

And override libvterm-neovim for the actual neovim package

neovim-flake.packages.x86_64-linux.default.override {
  libvterm-neovim = nixpkgs-staging.legacyPackages.x86_64-linux.libvterm-neovim;
};

it takes longer to rebuild but you can also just add to the input for the overlay:

neovim-nightly-overlay = {
  url = "github:nix-community/neovim-nightly-overlay";
  inputs.nixpkgs.follows = "nixpkgs-staging";
};

with nixpkgs-staging being the same as in the above comment

Is it possible to change the automation to only update the flake if it builds successfully?

Sure. Idk if I want it to be blocked if Darwin fails though, I have to look into that.

What do you mean by the last part

with `nixpkgs-staging` being the same as in the above comment

?

When I try to add the logic you mention in your post, I get errors that nixpkgs-staging doesn't exist. How exactly do you have to set the flake up to get this working with the temporary fix, cause I've tried everything and still cannot build.

Thanks!

@LSleutsky add the line nixpkgs-staging.url = "github:nixos/nixpkgs/staging"; below here

nixpkgs-staging just being nixpkgs from the staging branch (which currently has the good dependency)

i would link my config but it seems i forgot to push the changes after getting it working 😄

Ahhhh gotcha, duh! Thanks for the reply, works like a charm now...!

I've made it so updates are now made in the flake-update branch and are turned into a PR that gets rebased & merged into master once neovim builds for Linux. This means that the master branch from now on should always have a working Linux package, Darwin on the other hand can still be blocker as I make its failure ignore-able in CI as Darwin tends to be much more fragile. If enough people want me to set Darwin as a blocker too, I can agree to do that, just remember that until recently Darwin was failing for multiple months while Linux was not. I am also applying the temp workaround for the current build failure.

[Kranzes]

I am keeping this issue open until this gets resolved in the next staging bump in nixpkgs

Another quick solution is to just use overlays:

_: _final: prev: {
  libvterm-neovim = prev.libvterm-neovim.overrideAttrs (_: rec {
    doCheck = false;
    version = "0.3.3";
    src = prev.fetchurl {
      url = "https://launchpad.net/libvterm/trunk/v${prev.lib.versions.majorMinor version}/+download/libvterm-${version}.tar.gz";
      hash = "sha256-CRVvQ90hKL00fL7r5Q2aVx0yxk4M8Y0hEZeUav9yJuA=";
    };
  });

  neovim-unwrapped = prev.neovim-unwrapped.override {
    inherit (prev.llvmPackages_latest) stdenv;
    inherit (final) libvterm-neovim;
  };
}

....
<inside nixVim setup>

config = { package = pkgs.neovim-unwrapped; }

These are all basically worse than what I pushed to master earlier.

[Kranzes]

solved.
