devstack ubuntu broken pipe error (current and rocky)

Hi!

Seems I'm trying to do something a little less common which is install devstack on Ubuntu 18.04.02 LTS without doing a conjure-up or something similar. The machine is fully updated/upgraded. No new packages added. Git was already a part of the server install.

My goal is to do something like tripleo (OpenStack on OpenStack) on Ubuntu.

So the idea was install devstack on a single machine.

So did the git clone against master put a local.conf in, (even tried the exact example on this page (https://docs.openstack.org/devstack/latest/guides/single-machine.html)) ran "./stack.sh"

If I use master the error occurs on line 540. If I got to stable/rocky it appears on 533.

./stack.sh: line 533: echo: write error: Broken pipe

Not sure where to go from here. I checked for text file logs or logs to journalctl as the stack user and don't see them.

Thanks in advance!
