I have set up a server in a homelab using Proxmox, on top of Debian Trixie, thanks to the evangelizing of @stefano and @gyptazy (thanks fellas!).
All went fine, except Proxmox doesn't accept the only user on the Debian install before it. I used 'sudo' on the Debian install, therefore no root account.
Do I need a dedicated root user for #Proxmox to operate?
