Thanks for this bug report.
Your snippet above unfortunately skips the actual error that is happening.
Here is the relevant error:

I believe this is because of an outdated version of the
https://tracker.debian.org/pkg/golang-github-coreos-bbolt package, at least
upstream explicitly references version 1.3.3. I've filed #947617 for this.
