nix-darwin now uses release branches that correspond to Nixpkgs releases.
The nix-darwin and Nixpkgs branches in use must match, but you are currently
using nix-darwin ${nixDarwinVersion.release} with Nixpkgs ${lib.trivial.release}.
On macOS, you should use either the `nixpkgs-unstable` or
`nixpkgs-YY.MM-darwin` branches of Nixpkgs. These correspond to the
`master` and `nix-darwin-YY.MM` branches of nix-darwin, respectively. Check
<https://status.nixos.org/> for the currently supported Nixpkgs releases.
If you’re using flakes, make sure your inputs look like this:
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/NIXPKGS-BRANCH";
nix-darwin.url = "github:LnL7/nix-darwin/NIX-DARWIN-BRANCH";
nix-darwin.inputs.nixpkgs.follows = "nixpkgs";
# …
};
If you’re using channels, you can check your current channels with:
$ sudo nix-channel --list
nixpkgs https://nixos.org/channels/NIXPKGS-BRANCH
darwin https://github.com/LnL7/nix-darwin/archive/NIX-DARWIN-BRANCH.tar.gz
…
$ nix-channel --list
…
If `darwin` or `nixpkgs` are present in `nix-channel --list` (without
`sudo`), you should delete them with `nix-channel --remove NAME`. These can
contribute to version mismatch problems.
You can then fix your channels like this:
$ sudo nix-channel --add https://nixos.org/channels/NIXPKGS-BRANCH nixpkgs
$ sudo nix-channel --add https://github.com/LnL7/nix-darwin/archive/NIX-DARWIN-BRANCH.tar.gz darwin
$ sudo nix-channel --update
After that, activating your system again should work correctly. If it
doesn’t, please open an issue at
<https://github.com/LnL7/nix-darwin/issues/new> and include as much
information as possible.
