When I try to update GRUB, I receive the following error:

/usr/sbin/grub-mkconfig: 1: /etc/default/grub: Syntax error: ")" unexpected

Here is my GRUB config:

GRUB_DEFAULT=0

#GRUB_HIDDEN_TIMEOUT=0

GRUB_HIDDEN_TIMEOUT_QUIET=true

GRUB_TIMEOUT=10

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX=""



# Uncomment to enable BadRAM filtering, modify to suit your needs

# This works with Linux (no patch required) and with any kernel that obtains

# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"



# Uncomment to disable graphical terminal (grub-pc only)

#GRUB_TERMINAL=console



# The resolution used on graphical terminal

# note that you can use only modes which your graphic card supports via VBE

# you can see them in real GRUB with the command `vbeinfo'

#GRUB_GFXMODE=640x480



# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux

#GRUB_DISABLE_LINUX_UUID=true



# Uncomment to disable generation of recovery mode menu entries

#GRUB_DISABLE_RECOVERY="true"



# Uncomment to get a beep at grub start

#GRUB_INIT_TUNE="480 440 1"

The only difference between yours and my grub file is mine has

    # If you change this file, run 'update-grub' afterwards to update       

# /boot/grub/grub.cfg.      

# For full documentation of the options in this file, see:      

#   info -f grub -n 'Simple configuration'

But that shouldnt make a difference since the lines are commented out. I had an update which updated grub that told me the grub files were different and I kept the one from the update and I no longer had the error you were getting. So i recommend you check fir any updates.

Please make sure you are showing the correct grub file output.

I am running 16.04 here is a copy of my grub file

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

# For full documentation of the options in this file, see:

#   info -f grub -n 'Simple configuration'



GRUB_DEFAULT=0

#GRUB_HIDDEN_TIMEOUT=0

GRUB_HIDDEN_TIMEOUT_QUIET=true

GRUB_TIMEOUT=10

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX=""



# Uncomment to enable BadRAM filtering, modify to suit your needs

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

#GRUB_DISABLE_RECOVERY="true"

#GRUB_INIT_TUNE="480 440 1"

then you can use below to update

sudo update-grub
