[Bug 1539997] Re: package grub-efi-amd64 2.02~beta2-9ubuntu1.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127

Rather than add a second set of quotes, you need to just move it to be
within the first set.  That is, move the end quote to the end of the
line instead of being in the middle of it.

You can edit it by running "sudo nano /etc/default/grub" and entering
your password.
