I use Ubuntu 24 and I did try to install openstack, but it seems it's not the latest one.

}

That's the information I thought is good for the help.

And that's the error I have:

root@gregion83:~# openstack server rebuild --image 608349cf-8743-4339-8e2c-e707f89be64f --no-user-data c18f669d-1338-42dd-947f-c40217238450

I see this link from which I can install: https://docs.openstack.org/horizon/2025.2/install/install-ubuntu.html
