Bullseye on BBB

Hi everybody, This is my first post.
I’m sorry about my English, ain’t my first language.
I’ve try to upload Debian 11 on mi EMMC, following this site

the image is this

bone-debian-11.3-iot-armhf-2022-04-30-4gb.img.xz

All work fine, or I think that, but when I try to complete the last instruction

poweroff

I recive this error

System has not been booted with systemd as init system (PID 1). Can’t operate.
Failed to connect to bus: L’host non è attivo
Failed to talk to init daemon.

ok, no problem I’ switch off with power switch, taken off sd card, but, when a power on i?m not able to connect via ssh.

the ip is assigned by router, and is hold.

After firs start with sd, I’ve installed ufw and allowed port 22 and openSSH.

what’s wrong?

tks
