Ubuntu – Grub error: /usr/sbin/grub-mkconfig: 7: /etc/default/grub: splash: not found


Yesterday I'd installed new driver for my sound card and today the Sound doesn't work. I'd found an answer for this problem and fixed it in /etc/default/grub, but now when I try sudo update-grub it comes this error:

/usr/sbin/grub-mkconfig: 7: /etc/default/grub: splash: not found

This is 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_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX="splash quiet"

I add this line:

GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“

And I commented this line out:


I am using Ubuntu 16.04 LTS.

  • Please look closely at the line

    GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“

    You will see the should be ", perhaps you copied and pasted it from some where. Please re-write that line and use your keyboard don't copy and paste. And the line:

    GRUB_CMDLINE_LINUX="splash quiet"

    has its entry repeated in

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=use_crs"

    Make that line:
