With nix-channel --update; nix-env -iA nixpkgs.nix nixpkgs.cacert; systemctl daemon-reload; systemctl restart nix-daemon I was able to solve the following error:
trace: warning: You are using
Home Manager version 24.05 and
Nixpkgs version 23.11.
Using mismatched versions is likely to cause errors and unexpected
behavior. It is therefore highly recommended to use a release of Home
Manager that corresponds with your chosen release of Nixpkgs.
If you insist then you can disable this warning by adding
home.enableNixpkgsReleaseCheck = false;
to your configuration.
