I think you're using an older version of nixpkgs that didn't have this package yet - try:

nix flake lock --update-input nixpkgs

... and then rebuild your system again.

[LamprosPitsillos]

nix flake lock --update-input nixpkgs

will do and report back. Shouldnt nix flake update be enough ? I updated a few days ago

Shouldnt nix flake update be enough ? I updated a few days ago

It would be enough, but llvm17 has been merged just 5 days ago, so you've probably run that command 6 days ago or more 👀

[LamprosPitsillos]

It's now , fixed thanks!

This issue exists again for clang_17 and clang-tools_17. Same problem and expected result as above.

@donottellmetonottellyou, you're actually facing the same issue the original author did, i.e. you're using too old Nixpkgs.

7c6e3666e2040fb64d43b209b84f65898ea3095d is from Nov 29, 2023 - I'm guessing at some point you've just updated name inside the call to fetchGit, but it's rev which matters the most there.

[donottellmetonottellyou]

Wait what? What am I doing wrong here:

git ls-remote https://github.com/nixos/nixpkgs 23.11
7c6e3666e2040fb64d43b209b84f65898ea3095d        refs/tags/23.11

Oof, it looks like I was targeting the 23.11 tag, not the proper nixos branch:

git ls-remote https://github.com/nixos/nixpkgs nixos-23.11
219951b495fc2eac67b1456824cc1ec1fd2ee659        refs/heads/nixos-23.11

I officially feel like an idiot.

Yes, I had been checking the rev, and had been absentmindedly not noticing that it wasn't changing...

Posting this here so if anyone makes the same mistake (probably not) they see this.
