I use the flakes branch of nix (2.4pre20200721_ff314f1) and NixOS 20.03.20200808.d3a1eb0 (Markhor) and nixpkgs 1d8c4410687390f9b8f92dbe6ff39fd8fc2b17c6.
Since yesterday, when I run sudo nixos-rebuild switch I get this error:
error: --- Error -------------------------------------------------------------------------------------------------------------------------------------- nix
