[dpc]

With nix 2.21.3 our CI started failing unable to vendor new cargo deps:

       For full logs, run 'nix log /nix/store/yq9yfzmf7nvyq4nbb29fwm4a9zrgzq7r-jsonrpsee-types-0.24.0.drv'.

I suspect this is a Nix breakage as we've just upgraded our CI runners. Downgrading to 2.18 fixes the issue.

I don't expect this being immediately actionable, just wanted to notify. Chances are this is yet another Nix version breakage of which there were many in recent months.

Thanks for the report! Yes I have also experienced too much breakage on newer releases that I've taken to pinning my CI to use whatever is in nixpkgs-unstable (currently the 2.18.x series)...

As for this particular issue it seems like it was a DNS/networking issue?

As for this particular issue it seems like it was a DNS/networking issue?

We have multiple runs of the CI, separated by hours with the same behavior. It was reported not long after I did nixos update on all NixOS CI workers. And it fixed itself immediately after I downgraded to the 2.18.x. I'm 99% sure it's something about Nix version. Possibly not even crane's issue, so reporting mostly as a datapoint.

[ipetkov]

Definitely recommend reporting it to the Nix repo directly in that case!

[ipetkov]

Going to close this as I don't think there is much we can do here; still recommend opening an issue about this upstream!
