This is meant to work on a clean Debian installation. This playbook executes the steps outlined in
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm
Nothing more nothing less. When finished, you are directed (as in that documentation) to open the GUI and continue.
The part of this playbook that edits your /etc/network/interfaces file will discard the current settings and replace with a fresh new install of your main NIC configured with current settings as a bridge.
To run:
ansible-playbook proxmox.yml
If your server has an old P410 controller you may now proceed to the last step.
