I accidentally wiped /etc/default/grub with a mistyped :w !sudo tee %. Is there a way to regenerate its content? Is the original available somewhere to copy?

Surprisingly, that file /etc/default/grub/ doesn't seem to be provided by any package. I used dpkg -S /etc/default/grub, but it failed. However, you can copy the content of the default file from below. This file is same for Ubuntu 12.04 and 12.10.

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

# 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 ...)

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

# The resolution used on graphical terminal

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

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

  • God bless you. Do you know where I can find the original source? – fny Apr 4 '13 at 17:12
  • I have given the file's content in the answer. copy the contents and create a new file in '/etc/default' directory with 'grub' name. paste the content in the file and save it. note- you need root permission to do so – Anwar Apr 6 '13 at 14:32

    Content is still the same on 15.10 – Rinzwind Mar 4 '16 at 15:58

This worked for me:

sudo apt-get remove --purge grub-pc
sudo apt-get install grub-pc
