thank you so much , but i need an installation guide for antelope version of ubuntu , do you have any idea where i can find it ?

I recommend the latest LTS version (Ubuntu 22.04). This will be supported until April 2032

https://docs.openstack.org/install-guide/environment-packages-ubuntu.html
It is using Ubuntu 22.04 and adding the antelope version repository.
# add-apt-repository cloud-archive:antelope
Bobcat is the newest version for Ubuntu 22.04.

Installation guide for Openstack:

What's wrong with https://ubuntu.com/openstack/install ?
That is the installation guide of openstack on Ubuntu.

Quotes:
It will deploy an OpenStack 2023.1 (Antelope) cloud.
Requirements

"its an academic project"
Openstack is for deploying thousands if not hundreds of thousand virtual machines.
