Vanilla server?

I have read intro post: About the Installation Issues category
I have read the tutorials, help and searched for similar issues

Actually, I’m newbee, and I want to install passbolt on my ubuntu 22.04 server, so I need some more information about that vanilla server, is that we havn’t to install web server and database before we start insttalling with this tutorial Passbolt Help | Install Passbolt CE on Ubuntu 22.04

A vanilla server is one where you haven’t installed anything else other than just the linux OS. So, if you just provisioned a VM or installed Ubuntu on a server you are ready to go!

Thanks you that was understood.
