bug#28087: "guix build: error: no build log for gnu-store-pathto.drv" with previously offloaded successful build

Hi ng0,

Sorry for the late reply.

Note: don’t use “--log-file” along with “--check”; these are two
different things.

Can you still reproduce this?

If so, can you manually check whether the log file you’re looking for is
actually in /var/log/guix/drvs on your machine?

TIA,
