update-grub does'nt go on

[dstc]

Good evening

i edit /etc/default/grub and i comment quite splash

GRUB_CMDLINE_LINUX_DEFAULT= # ‘’quite splash’’ commenté le

i enter update-grub.

With linux mint lmde2 betsy mate all is alright a message is displayed saying

/boot/vmlinuz-3,16,0-4-amd64, /boot/initrd… et memtest8+ … ont été trouvés…
etc...

and the os starts not quitely and without splash

but with buntu 14,4 and with linuxmint 18,3 sylvia i get following message :

/usr/sbin/grub-mkconfig : 1 : /etc/default/grub : # : not found

(not with a small n)
the os start quitely and with that stupid splash

why does ubuntu and linuxmint fail to upgrade grub ?

Place the # sign at the very left of the line. which you want to comment out.

also you must elevate to root privilege.
sudo update-grub

good afternoon
thanks a lot for your replays.
it is of cause with sudo, if not it will warning and not start.
i tried with # in front but it doesn't help.
with mint lmde and earlier distribution of linux mint or ubuntu you are allowed to put # after the equal sign and it worked.

~$ less /etc/default/grub

~ $ sudo update-grub

i guess something goes wrong with update-grub with ubuntu and similar upgraded version.
i tried to look in /usr/sbin/grub-mkconfig but it is hard for me to understand how it works.
