Thank you all. All comments very much appreciated. Here is how we attempt to install:
- we start from a minimal CentOS 7 install, latest and updated on the undercloud machine
- the network is pretty much standard from the manual and is available here: https://drive.google.com/file/d/1x57_tmMU9yOaJlFFepn3-gNASTR-oI1R/view?usp=sharing
- we follow closely the TripleO instal manual
- repos are enabled with: sudo yum install centos-release-openstack-rocky

This may be the problem - you should use the tripleo-repos tool to
ensure the latest/correct RDO repos are enabled, I don't think we
document centos-release-openstack-rocky anywhere in the tripleo docs?

https://docs.openstack.org/tripleo-docs/latest/install/installation/installation.html#installing-the-undercloud

As I retrace our steps into what caused the installation troubles in the first place I notice the following in the undercloud install manual:

At bullet point "2. Enable needed repositories" and under the RHEL box

"Download and install the python2-tripleo-repos RPM from the current RDO repository. For example"

"sudo yum install -y https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-<version>.el7.centos.noarch.rpm"

What should <version> be? rocky? Then the install fails with

[root@pallas ~]# yum install https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-rocky.el7.centos.noarch.rpm
Loaded plugins: fastestmirror
Cannot open: https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-rocky.el7.centos.noarch.rpm. Skipping.
Error: Nothing to do

Looking at https://trunk.rdoproject.org/centos7/current/ I see that there is a python2-tripleo-repos-0.0.1-0.20181218212820.a5b709e.el7.noarch.rpm. Is this the one?

best wishes.
