Describe the bug

nix crashes when rebuilding my flake based configuration. This is the second time this specific errors to me but it is not deterministic as rerunning the same command succeeds afterwards.

Steps To Reproduce
Too many custom repos involved. I hope the backtrace is enough.

I've also been observing this on a bunch of systems. The weird thing is, restarting the same build a second time seems to just work?

Huh, the two assert(newInfo.ca) in derivation-goal.cc look good to me. Are you repairing or checking paths by any chance?

Ericson2314 picture Ericson2314 on 13 Nov 2020

I am just running a nixos-rebuild, at some point it's possible it calls builtins.pathExists.

teto picture teto on 13 Nov 2020

something I've noticed is that happens after I rebase on nixos-unstable. It rebuilds something and fails once, then I restart the command and it works fine until the next rebase.

Hmm, that does sound like something to do with fixed output derivations.

Ericson2314 picture Ericson2314 on 24 Nov 2020

Just came across the same error while running nixops, also appears to be nondeterministic. I'm way out of my depth here but thought I'd post some of my info in case it's to any use.
