Open Stack

Hello,

I tried to create Murano image for an openstack Victoria deployment following the document available at, 

https://docs.openstack.org/murano/victoria/reference/appendix/articles/image_builders/linux.html

But unfortunately was not able to successfully create an image.

At first the following error occured:
"murano-agent requires Python '>=3.6' but the running Python is 2.7.17"

Then after changing the release to focal, receive another error:

"Unable to locate package python-pip"

We(me and my colleague) are kind of block for the deployment of Murano application service, is anybody so kind to help us with this problem? I am attaching the commands ran and terminal output below for reference. 

Looking forward for your quick response, many thanks in advance.
