I also am getting some evaluation warning on system but cant seen to locate which file raises this problem:
evaluation warning: 'system' has been renamed to/replaced by 'stdenv.hostPlatform.system'
This might be the reason because its saying unknown on the derivation of the error
Anyone have the same error? or some idea how to fix/debug this?
[UPDATE] I figured out the problem
It had no relation to that evaluation warning about system, after this evaluation was fixed i was still not able to update.
The reason for the error comes from swww package that i was using, it was archived and moved to codeberg with a different name: awww.
After updating the flake inputs with the new url and renaming swww to awww everywhere on my config, everything seems to be able to build alright again.

Hey! How did you manage to get rid of the warning? I’m getting the same, but because it has no info about the file and my config is pretty modular, I’m not sure which of all the “systems” is the offending one (system.stateVersion? nixpkgs.lib.nixosSystem { inherit system } ? I tried both without success

Hi!
Try searching through all configuration files where pkgs.system might be used.
grep -r "\bpkgs\.system\b" ~/.setup # replace setup with your configuration directory
I had it in a couple of places myself:
/home/stepan/.setup/hosts/_shared/boot/loader.nix: theme = inputs.distro-grub-themes.packages.${pkgs.system}."${cfg.grubTheme}-grub-theme";
Accordingly, it needs to be replaced with pkgs.stdenv.hostPlatform.system.

That helped a lot!
For the record, I was using it inside a
with pkgs; [ inputs.my-input.packages."${system}".default ]
block.
Hey sorry for the late reply, but yeah just as MOIS3Y said.
For me it was even harder to find btw, i was importing another flake of mine (for neovim) that had the problems, most of the errors was from outside my repo and i had no idea haha.
Well at least its fixed, only the system problem tho, as for rust-docs, there is something more that i gotta do that im still figuring it out. For now i downgraded my Yazi and Hyperland to use the packages from nixpkgs instead of their respective flakes.
For yazi i opened an issue here: Build error on flake: do not know how to unpack source archive · Issue #3312 · sxyazi/yazi · GitHub
[update]
i didnt have sww installed and also i dont have yazi but the problem still exist

Your logs tell you what’s indirectly pulling it in (lanzaboote). Report it to them.

Had the same error. Also using the lanzaboote flake. Turns out you need to update it: Release v0.4.3 · nix-community/lanzaboote · GitHub
This solved the problem for me.
