Forcing the boot menu to wait for manual selection

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:

Code:

su -

password:

Code:

su

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 -
