Log after a poweroff created by sudo journalctl -b -1 | grep -i
"halt\|power.off\|shutdown\|reboot"
My computer with Ubuntu server 26.04 never stay off, it always restart on it's
own.
Tried with 'sudo poweroff' and 'sudo shutdown -h now' and the physical button.
Later tried 'sudo halt' that causes a black screen where I had to poweroff with
the button
