Can't update to nixos-unstable

Help
1

originally I had my nixos channel alias set to nixos-24.11

I now have two channels, nix-hardware (from github) and nixos-unstable (alias nixos)
but I can’t build it. I keep getting an error.

i’ve tried including the python313Packages.setuptools package in my configuration.nix but it didn’t change anything.

what’s going on and what do I need to do to fix it?

That won’t work, remove it.

Report it on github at https://github.com/NixOS/nixpkgs/issues if no one else has and assuming it’s not been fixed yet on master.
setuptools should be part of build-system, though it’s unclear why this wasn’t caught earlier.

the program “manim” was messing with it, removing it fixed the issue, now I need to see if it isn’t available for the unstable channel.

It’s fixed in python3Packages.manim: fix build by Defelo · Pull Request #380526 · NixOS/nixpkgs · GitHub.

@waffle8946 i’m relatively new to Nixos, how would I go about installing that fix?

The easiest way is to just wait. After some time the change will go into the nixos-unstable branch and you can add it back.

As said, just wait until this reaches nixos-unstable, which should be soon: https://nixpkgs-tracker.ocfox.me/?pr=380526
