Unfortunately this is the second time we've had to learn it :-(
commit 5b9b49d7bd3e0da13e8f6d58578443a11817f56e

docker: change Fedora base image to fedora:27
Using "fedora:latest" makes behavior different depending on when you
actually pulled the image from the docker repository. In my case,
the supposedly "latest" image was a Fedora 25 download from 8 months
ago, and the new "test-debug" test was failing.
Use "27" to improve reproducibility and make it clear when the image
is obsolete.
Regards,
Daniel
