Bug#931896: grub-efi-amd64: symbol `grub_file_filters` not found

[Balasankar "Balu" C]

Hi,

I was also hit by this bug after upgrading yesterday (it has been few
weeks since I updated the machine). Just like others, I also had to
downgrade the following packages to 2.02 to get it working.

1. grub-common
2. grub2-common
3. grub-efi-amd64-bin
4. grub-efi-amd64
5. grub-pc-bin

AFAIK, my installation of Debian was pretty straightforward and I
haven't tinkered with grub after installation at all. If anything caused
GRUB misconfiguration, it is probably Debian Installer.

Provided that multiple people are facing the same problem, maybe a bit
more investigation would be helpful to know more about why this suddenly
popped up, what is common with all these users' configuration, and
whether it is a legit issue, etc.?
