Thanks for the ping. Once #575 is rebased, we can merge it.

Wow, terrible user experience out of the box, especially considering #594 and when you are not running fedora.

Building in a container doesn't seem to have worked since v0.1.32, from Nov 7 2018.
This Issue was opened Jan 9 and #575 is from Dec 16 2018 as well... Please fix this simple thing.

Since the PR is merged, I will close the issue.
