Bug#845023: efibootmgr: Could not prepare Boot variable: No space left on device

[Vladmimir Stavrinov <vstavrinov@gmail.com>]

Package: efibootmgr
Version: 14-1
Severity: critical
Tags: upstream
Justification: breaks the whole system

Dear Maintainer,
The error in subject is issued by the command:

efibootmgr -c -L Debian -l /boot/grub/x86_64-efi/grub.efi

and this makes system unbootable. I have found a lot of reports about this
problem, but no solutions. This has happened a month or more ago while system
upgrade though there was not such problem before.  And it is obvious it is not
space problem, because nothing changed there, and EFI partition is used for 25%
only.
