[SOLVED] Forcing the boot menu to wait for manual selection

PaulExordium · 04-30-2021, 11:10 AM

In Debian 10 modifying the "GRUB_TIMEOUT" parameter to -1 and then running "update-grub" leads to an error and the boot menu has the same behavior. See below.

Code:

1) Uncommented part of /etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT=-1
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""


2) Content of script /usr/sbin/update-grub

#!/bin/sh
set -e
exec grub-mkconfig -o /boot/grub/grub.cfg "$@"


3) As root in /usr/sbin

ls -l *grub*
-rwxr-xr-x 1 root root 1041064 Mar  1 23:50 grub-install
-rwxr-xr-x 1 root root  804664 Mar  1 23:50 grub-macbless
-rwxr-xr-x 1 root root    8023 Mar  1 23:50 grub-mkconfig
-rwxr-xr-x 1 root root  217528 Mar  1 23:50 grub-mkdevicemap
-rwxr-xr-x 1 root root  821368 Mar  1 23:50 grub-probe
-rwxr-xr-x 1 root root    4112 Mar  1 23:50 grub-reboot
-rwxr-xr-x 1 root root    3562 Mar  1 23:50 grub-set-default
-rwxr-xr-x 1 root root      64 Feb 27 16:07 update-grub
lrwxrwxrwx 1 root root      11 Mar  1 23:50 update-grub2 -> update-grub

./update-grub
./update-grub: 3: exec: grub-mkconfig: not found

What am I missing?

set to this or longer

Code:

GRUB_TIMEOUT=10

Reread your post, misread your post first time around. Did you su into root? if so did your run

Code:

su
password:

or

Code:

su -
password:

Code:

su
password:

will result in the error your seeing.

It was with

Code:

su root
password:

that I did all wthat I've described in my first post.

^This is what caused your problem. As colorpurple21859 said, you had to call su with a dash: su -
