get error running update-grub

[Bob]

I updated /etc/defaults/grub to add "GRUB_RECORDFAIL_TIMEOUT=10" so that a
beboot after a failure will not stop waiting for someone to press a key.  I
want all boots to complete without intervention even after a power failure.

Running "update-grub" I get the following error:

My question is what should the values be for /etc/default/grub since the real
defaults are not completely correct?
