VirtualBox 7 installation tutorial not working

Hi,

I followed thoroughly that tutorial https://ubuntu.com/tutorials/how-to-...box#1-overview
But it's not working for me.
Unattended installation gives me an error "systemd-journald[2515]" : Failed to send WATCHDOG=1 notofication message: Transport endpoint is not connected connected"
(Would like to send you screenshots but uploading attachements doesn't seem to work...)

As for attended install, it gives me "[drm:vmw_host_printf] *ERROR* Failed to send host log message", then shows an endless graphical loading screen.

Any clue?

Using latest VirtualBox 7.0 on MacOs Catalina, and latest Ubuntu ISO 22.04.2-desktop-amd64

Thanks!
