Ok, i've been struggling with this for couple of days now, googled everything I could, but still can't find an answer. When I lunch Grub Customizer in Ubuntu 10.04, i get this error message:

grub-mkconfig couldn't be executed successfully.

My bad, I'm running it in Ubuntu 12.04

Wyatt Smith (wyatt-smith) said : #2

The proper way to update the grub,cfg file is with the following command
sudo update-grub

Jeet (gour-jitendrasingh) said : #3

is the same for 12.04

sudo grub-mkconfig
sudo grub-update

what is the output of lb_release -a; uname -a


Stan Kapelkin (slavyan) said : #4

That's the whole problem, the sudo update-grub does not work, it keep giving me this error:
sudo: update-grub#: command not found

Stan Kapelkin (slavyan) said : #5

btw, the uname -a gives me this:
Linux kristina-VGN-NW125J 3.2.0-24-generic-pae #37-Ubuntu SMP Wed Apr 25 10:47:59 UTC 2012 i686 i686 i386 GNU/Linux

Jeet (gour-jitendrasingh) said : #7

i suspect grub2 is making problem

Wyatt Smith (wyatt-smith) said : #8

Hard to tell if it is something with grub or a problem with your path environment variable. Try...
sudo /usr/sbin/update-grub

Jeet (gour-jitendrasingh) said : #9

what does command
sudo grub says ??

Jeet (gour-jitendrasingh) said : #10

yes Wyatt can be right try running command
sudo /usr/sbin/update-grub

and also provide output of

sudo grub


Wyatt Smith (wyatt-smith) said : #11

If the last command I gave you fails please tell the output of
echo $PATH ; ls /usr/sbin/ | grep grub

Stan Kapelkin (slavyan) said : #12

yeh both sudo /usr/sbin/update-grub and sudo grub (command not found).

output of echo $PATH ; ls /usr/sbin/ | grep grub:


Wyatt Smith (wyatt-smith) said : #13

Path environment variable is ok. Grub files exist. Files might not be executable. Lets check
ls -l /usr/sbin/ | grep grub

Wyatt Smith (wyatt-smith) said : #15

That is very strange, you should not be getting command not found. The files are in you path and are executable. It does look like there are some links though. I suggest reinstalling grub

sudo apt-get install grub-pc --reinstall

Stan Kapelkin (slavyan) said : #16

Looks like there is a problem with re-install as well:

Jeet (gour-jitendrasingh) said : #17

grub-pc will install grub2 if you want to change to old GRUB you can remove grub 2

please follow that

Jeet (gour-jitendrasingh) said : #19

you can check your current grub version with

sudo grub-install -v

GRUB2 will have version 1.99 and later


Stan Kapelkin (slavyan) said : #20

Followed the link, but again after running sudo apt-get install grub-pc, i'd get "sudo: update-grub#: command not found" error

This is so frustration, i've been hunting for an answer all this time and not sure if I'll find one. It seems that whole Ubuntu 12.04 installation has a problem or something. Wonder if I can re-install it into previouse version as 12.04 seem to be buggy.

BTW, sudo grub-install -v gives me:

sudo: update-grub#: command not found
grub-install (GRUB) 1.99-21ubuntu3

Jeet (gour-jitendrasingh) said : #21

try this

sudo grub-install /dev/sdX (where X is drive later where you installed Linux)


Jeet (gour-jitendrasingh) said : #22

remember do not add drive number .. it can generate error...

for example

sudo grub-install /dev/sda

Thanks and revert if unclear

Stan Kapelkin (slavyan) said : #23

Jeet (gour-jitendrasingh) said : #24

If you did then i suggest you to report bug...

Still problem with grub. I create a bug.

Barry Drake (b-drake) said : #26

I can't understand why you have a # character at the end of sudo update-grub Am I to understand that you are entering it with the # character? If so, the command update-grub# does not exist. Try again without the #.

Stan Kapelkin (slavyan) said : #28

Ended up dumping Ubuntu 12.04 and installing Ubuntu 10. Have no problems with grub now. Seems like Ubuntu 12.04 still needs to be worked on.

Can you help with this problem?
