nixos-rebuild error: function 'anonymous lambda' called with unexpected argument 'nix'

[ddogfoodd]

Describe the bug
When trying to rebuild nixos with the latest nixos-unstable changes there is an error, which I assume might occur due to devenv 1.1 making it into nixos-unstable.

Here is the error message:

Version

Current version I have installed is 1.0.8
This error occurs when trying to update to 1.1

In case this issue should be opened in the nixpkgs repo instead, let me know and please excuse me posting it here.
Also let me know you cannot reproduce and I can provide further help via logs etc.

@ddogfoodd I confirm, have the exact same issue. Maybe will use upstream for now.

[devusb]

@ddogfoodd are you using Lix? If so, believe there's a conflict between this bit in their overlay and this nixpkgs PR that causes this issue -- the PR removed nix as an input to the devenv derivation, but the overlay still passes it.

I think the overlay is no longer necessary since the nix version is now explicit in the devenv package -- planning to open a PR to the Lix repo but haven't had a chance yet.

Thanks @devusb

https://git.lix.systems/lix-project/nixos-module/pulls/34 fix is in main, sounds like a release with it is still pending.

[ddogfoodd]

Fixed as of lix 2.91.1-1

[BreakingTV]

Running on lix version 2.91.1, still getting that error message...
Is there some other fix?

[ddogfoodd]

@BreakingTV You have to use the lix version 2.91.1-1
