Open Stack

Hi Pierre, thanks for replying to my message.

To install kayobe I followed the documentation which summarise: installing
a few system packages and setting up the kayobe virtual environment and
then pulling the correct kayobe git version for the openstack to be
installed. After configuring the yaml files I have run these commands:

- kayobe control host bootstrap
- kayobe overcloud host configure -> this one is failing with
/usr/libexec/platform-python: not found

After reading your message on the weekend I concluded that maybe I had done
something wrong. Today, I re-pulled the kayobe wallaby git and manually
transferred the configuration over to the new directory structure on the
ansible host and set up again as per the guide but the same issue is seen.

What I ended up doing to try and resolve was finding where this
"platform-python" is coming from. It is coming from the virtual environment
which is being set up during the kayobe ansible host bootstrap. Initially,
I found the base.yml and it looks like it tries to match what the host is.
I noticed that there is no ubuntu 20 listed there so I created it however
it did not resolve the issue.

So then I tried systematically replacing this reference in the other files
found in the same location "venvs\kayobe\share\kayobe\ansible". The file I
changed which allowed it to progress is "kayobe-target-venv.yml"

But unfortunately it fails a bit further on, failing to find an selinux
package [1]

Seeing as the error is mentioning selinux (a RedHat security feature not
installed on ubuntu) could the root cause issue be that kayobe is not
matching the host as ubuntu? I did already set in kayobe that I am using
ubuntu OS distribution within globals.yml [2].

Are there any extra steps that I need to complete that maybe are not listed
in the documentation / guide?
