POWER OFF COMMAND DOES NOT WORK on 22.04

2 issues impacting basic Linux features:

First issue: Since I've upgraded to 22.04 my 2 NUCs, (from 18.04 and 20.04) both of them are unable to be powered-off by the command line. Neither the command

sudo poweroff

nor the command

sudo shutdown -P now

are doing the job. The NUC are always rebooting instead. The only 2 ways to switch them off is

  1. unplug the powercord
  2. USE the windows manager GUI command (upper button on the right corner of Standard 22.04 windows manager.

2nd Issue: GRUB_TIMEOUT delay parameter placed into /etc/default/grub does not have any effect (Grub 2.06)!

As these 2 NUC should host network services and virtualization, they are not supposed to get windows manager but just a ssh services. Please can you help me to find a fix. Power off and shutdown are basics for many decades!

Please don't ask the same question again and again. [22.04 Server automatically reboots after sudo shutdown -P now or with sudo power off instruction](https://askubuntu.com/questions/1433700/22-04-server-automatically-reboots-after-sudo-shutdown-p-now-or-with-sudo-power)

Check your UEFI settings. Power State set to Always-on will automatically power-on if a usb adapter is connected. When changing grub.cfg does not take effect, maybe grub is using some other root than you expect -- could you have some other root which really controls the grub menu?

Keep calm :)

shutdown -h now

This will effectively halt your system.

As for the Grub timeout, after you have edited/etc/default/grub

sudo update-grub

Is required to notify the bootloader about your changes.

Good luck!

history | grep grub reports:

1797  sudo vi /etc/default/grub && sudo update-grub
1821  sudo vi /etc/default/grub && sudo update-grub

shutdown -h now is not running better than poweroff cmdline, my parameters are:

GRUB_DEFAULT=0
#GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
