I haven't seen this before and couldn't find any bug report in the cachix repo. The easiest would probably be to make this a step that can fail without making the entire test fail. I restarted the linked test to make sure it's a flake.

Cachix is borked and disabled on our self-hosted runner, AFAIK. I reported an issue on cachix action repo. Re-enabling it makes it upload tons of stuff on every run.

Mac isn't self-hosted though afaik.

Oh. I missed that part.

cachix/cachix-action#185

Hopefully this gets fixed soon, dependabot will update this action automatically, will re-open if it still is bothering us.
