update-grub command not found

 

 

he update-grub command was created to make things easier - it is simply a shell script in /usr/sbin/:



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

 

 

If it is not there, you can make your own. To do that, run this, and paste in the above script:

sudo nano /usr/sbin/update-grub
Save with Ctrl+O, and exit with Ctrl+X.

Then run these:

sudo chown root:root /usr/sbin/update-grub
sudo chmod 755 /usr/sbin/update-grub
And you should now be able to run update-grub. :-)
