I think it's related to NixOS/nix#3605

[vcunat]

It succeeded after restarting. (so the log above got overwritten, too)
We also had some transient failure on x86_64-linux.

And now it fails again due to aws-sdk-cpp-nix.

It succeeded after restarting 🤷🏽

Just had the same failure on recent master (68403fe04f6c85853ddd389c9e58dd9b9c8b0a36)

will try to restart and see if it helps

EDIT: didn't help

[vcunat]

Now the same build succeeded after restarting: https://hydra.nixos.org/build/206157991
(at least I think it was the same one)

Appears to be solved now! @wegank I'm closing because it looks like it was transient, but feel free to reopen.
