Subject: bug#33262: guix fails to find and use some available substitutes
Date: Mon, 05 Nov 2018 09:26:25 +0100

I think guix' message is a bit confusing: the .drv file is always created by guix, it's the derivation. The derivation is built, which results in a new store path. It can be built locally or by using a substitute. What you see in your store is the derivation (.drv), not its result. You can open that file to find where the result will be stored and check if it exists on your machine.
