[Bug 1871963] Re: dpkg fails to install grub-efi-amd64 signed and shim-signed

It looks like there is an extra ';;' in the script, the following patch

I do get a warning that "The GRUB boot loader was previously installed
to a disk that is no longer present, or whose unique identifier has
changed for some reason." I haven't changed the disks on my system or
done anything else that should trigger this.
