Grub Rescue error: symbol "grub_is_lockdown" not found

[manjotsc]

Hi,

I just installed the recent updates via UI, (Community Edition).

I am keep getting to grub rescue :

error: symbol "grub_is_lockdown" not found.
Enterting rescue mode...
grub rescue>

I am able boot the server, using Promox Installation Media, Rescue Boot under Advanced Options.

It just that the server cannot boot on it own.

Thanks,
Manjot
