bug: kanshi breaks nixos-rebuild

[jkaye2012]

Are you following the right branch?

• [X] My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• [X] I have searched the existing issues

Issue description

I think a recent commit might have inadvertently broken NixOS builds (or I'm doing something incorrect):

error:
       … while calling the 'head' builtin

         at /nix/var/nix/profiles/per-user/root/channels/nixos/lib/attrsets.nix:967:11:

          966|         || pred here (elemAt values 1) (head values) then

             |           ^
          968|         else

       … while evaluating the attribute 'value'

         at /nix/var/nix/profiles/per-user/root/channels/nixos/lib/modules.nix:809:9:

             |         ^
          810|         inherit (res.defsFinal') highestPrio;

       (stack trace truncated; use '--show-trace' to show the full trace)

       error: attribute 'attrTag' missing

       at /nix/store/gd2i9ncq2rswcwwai1f5wh0jbz4nl9iz-source/modules/services/kanshi.nix:9:19:

           10|     profile = mkOption {

Builds on this machine were functional last night. A build this morning with identical configuration (save for the home-manager version upgrade) fails with the message above. I believe that this change might be the cause.

Yeah, you need to update your nixpkgs. The change uses the new lib.types.attrTag which has been merged in nixpkgs' master branch on April 9.

Thanks - I didn't realize that channels had to be manually updated! Still learning over here. Appreciate the help

Hi, still failing even if I try to update nixpkgs-unstable channel. What command to run in order to update the nixpkgs?

[jkaye2012]

I ran sudo nix-channel --update and my previously failing build started working.

With that command, I had to add --upgrade to nixos-rebuild switch to made it work.

sudo nixos-rebuild switch -I {blahblah} -j 4 --upgrade
