Seeing the following in chefspec tests after running bundle update. Pinning chef to ~> 12.5.0 makes it go away.

@luckymike @martinisoft care to validate this? I'm still unsure about the underlying cause.

Tried to test this, but doing a bundle update pins me back to 12.3...

Okay, I think the bundle update thing was a symptom of a Ruby Gems service degradation. I see this with 12.8.1, and this pin to 12.5.1 works for me.
