Flake follows a non-existent input

[andmald922]

Whenever I attempt to update my flakes I keep getting the error: error: input 'hyprland/hyprland-qtutils/hyprutils' follows a non-existent input 'hyprland/hyprland-qtutils/hyprlang/hyprutils'

If I had to guess it might have something to do with #10 ? But I don't actually know. Never had any issues with installing or updating hyprland before this point

Heres my flake.nix in case it helps:

Sounds like lockfile shenanigans. Can you remove flake.lock and then run nix flake update again?

[sora-g22]

Removing my flake.lock from /etc/nixos did not fix the problem, is there a flake.lock in a different folder I should remove instead?

[sora-g22]

Kept researching, an even more drastic approach seems to have worked. I had to rm -r ~/.cache/nix before I could get the update to work again. Hopefully this will pop up in search results in case anyone experiences this as well. I would mark this as solved now but it seems I do not have permission to do so

[sora-g22]

Nevermind, I was able to update after I deleted the cache, but its still happening. If I attempt to run nix flake update it still occurs, this with a new flake.lock in my /etc/nixos directory and completely refreshed cache. I really have no idea whats going on here now

[fufexan]

I'm really not sure what might be causing it. Seems to work fine for most of us. What's your Nix version? I could not repro with pkgs.lix or pkgs.nix in unstable.

Maybe its something in my configuration.nix? I have no idea why it would cause an issue in a flake lock file but worth a shot?

That's unlikely. I don't see anything that could interfere.

[sora-g22]

Just checked back, realized you asked for my version of nix rather than nixos, my apologies, nix-info says I'm currently running 2.15.1

[sora-g22]

I was wondering why that version was so old, I didn't realize you had to run nix upgrade-nix as a whole separate command. Why is that not automatically updated with the rest of the system? Well, regardless, once I update nix the package this issue doesn't appear anymore. If I had to guess the way the follows are set up now are not backwards compatible with older versions of nix (EDIT I'm not sure what version of nix is needed, but it may prove useful to mention somewhere in the documentation a minimum version requirement)

[fufexan]

2.15 is pretty old. I wasn't even aware that anyone may still be using it. What I'm certain of is that 2.18+ should work fine. Not sure about the versions in between.

I didn't realize you had to run nix upgrade-nix as a whole separate command.

I'm almost certain that's an anti-pattern on NixOS. Should be handled by the nix.package option.

[sora-g22]

I'm almost certain that's an anti-pattern on NixOS. Should be handled by the nix.package option.

Whats crazy is that I set nix.package to version 2.25 before I tried doing it imperatively, didn't do anything when I rebuilt. Don't quite understand how I've managed to mess up my OS this badly, but at least I can update my flakes properly again

[fufexan]

My guess is that the imperative Nix is installed in a user profile and takes precedence in PATH.
