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

[J. Pietschmann]

Hi,

I have a similar problem with plain grub-pc (no EFI)
I use the first two HDD as an MDM array and installed grub
on both /dev/sda and /dev/sdb. A few weeks ago the first HDD
failed and was replaced, and I used
 update-grub
 grub-install /dev/sda
afterwards and could reboot the computer without problems. The next
reboot after the upgrade to grub 2.04 failed with
 symbol `grub_file_filters` not found
The grub update didn't show anything interesting on the console or
dpgk.log
The problem appears to be that grub 2.04 uses only devices by disk-id
and didn't install on /dev/sda even though grub 2.02 did.
Fortunately
 dpkg-reconfigure grub-pc
fixes the calamity.
What's the preferred way to reinstall grub on a new disk with 2.04?
Preferrably non-interactive/scriptable.

Cheers
