NixOps does not work with Nix 2.0

[Baughn]

Let's round up assorted bugs here. Only one I've spotted so far, but I'll probably find more.

• attribute ‘nixosVersion’ missing, at nix/eval-machine-info.nix:284
  These attributes have been renamed to nixos.version and so forth.

...hmm. On second thought, I'm not sure the one bug I found so far is a Nix 2.0 bug per se. The timing is suspicious, but it might be coincidence.

I'm stuck with the same problem

I duck-taped the issue with the following override in my personal overlay:

  nixops = super.nixops.overrideDerivation (
    old: {
      patchPhase = ''
        substituteInPlace nix/eval-machine-info.nix \
            --replace 'system.nixosVersion' 'system.nixos.version'
      '';
    }
  );

Stuck with the same problem. (@seppeljordan the patch helped, thanks)

I'm a newbie at this, I have ~/.config/nixpkgs/overlays/nixops.nix containing

self: super: {
  nixops = super.nixops.overrideDerivation (
    old: {
      patchPhase = ''
        substituteInPlace nix/eval-machine-info.nix \
            --replace 'system.nixosVersion' 'system.nixos.version'
      '';
    }
  );
}

Using nixpkgs https://nixos.org/channels/nixpkgs-unstable on Debian.

I presume I have something basic wrong in either the file location or contents. Any tips?

There's nothing immediately wrong with this... You do you use it? Did you try to run nix-shell -p nixops ? Does it pick up the modified version? Le 28 février 2018 17:53:54 GMT+02:00, Alan Zimmerman <notifications@github.com> a écrit :

@jpotier thanks, it does actually work, I had been switching channels and not properly updated, when I ran nix-shell -p nixops it brought in the current version again, and the overlay works as expected. Thanks.
