sudo shutdown now
Yes. You need to be a sudo user or root to shut down a Linux server because it is an administrative task.
Some people prefer to use
shutdown -h now but that's not required as both refer to power-off.
Keep in mind that you must have a way to power it on back again otherwise prefer to reboot remote Ubuntu servers.
How to shutdown Ubuntu server

1. Poweroff Ubuntu using shutdown command
You can use the shutdown command without any options. This will schedule a shutdown a minute from your current time.
You can cancel the scheduled shutdown with option
sudo shutdown -c

sudo systemctl poweroff
