Stripped the first
/etc, so the second source package name search is for

Do I have this file still on my Ubuntu machine?
$ sudo ls /usr/share/grub/default/grub
or, for example:
$ sudo [ -f /usr/share/grub/default/grub ] && echo Found || echo Not\ found

And what are its contents?
$ sudo cat /usr/share/grub/default/grub

# 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 disable graphical terminal (grub-pc only)
# The resolution used on graphical terminal

As you might have spotted there is one more obvious different line compared to the output from Rinzwind's answer:
