You are deploying Hercules CI Agent on a system with an incompatible
nix-daemon. Please
- either upgrade Nix to version 2.4.0 (when released),
- or set option services.hercules-ci-agent.patchNix = true;
- or set option nix.package to a build of Nix 2.3 with this patch applied:
https://github.com/NixOS/nix/pull/3405
The patch is required for Nix-daemon clients that expect a change in binary
cache contents while running, like the agent's evaluator. Without it, import
from derivation will fail if your cluster has more than one machine.
We are conservative with changes to the overall system, which is why we
keep changes to a minimum and why we ask for confirmation in the form of
services.hercules-ci-agent.patchNix = true before applying.
nix-daemon. Please make sure nix.package is set to a Nix version of at
least 2.3.10 or a master version more recent than Mar 12, 2020.
