I'm going to guess this is a docker build problem based on local configuration.. (Docker version 19.03.13, build 4484c46d9d)

I don't see quiet anywhere, but there is a -q in build/.

It builds after running docker buildx uninstall

[hasheddan]

@displague just wondering, if you run with DOCKER_BUILDKIT=1, does it build even with buildx installed? Also, does this PR look good to you? Looks like I can merge, but was waiting for explicit approval 🙂

@hasheddan with DOCKER_BUILDKIT=1 it still fails.
