Bug#962594: grub-efi-amd64: GRUB-EFI reprots: /dev/sda: open failed

[Heinrich Schuchardt]

Package: grub-efi-amd64
Version: 2.04-7
Severity: minor

Dear Maintainer,

update grub-efi creates messages:

Removing linux-image-5.4.0-4-amd64 (5.4.19-1) ...
/etc/kernel/postrm.d/initramfs-tools:
update-initramfs: Deleting /boot/initrd.img-5.4.0-4-amd64
/etc/kernel/postrm.d/zz-update-grub:

   /dev/sda: open failed: No medium found
   /dev/sda: open failed: No medium found
   /dev/sda: open failed: No medium found
   /dev/sda: open failed: No medium found

This does not make any sense since I have only 2 NVME devices installed:

$ lsblk

     └─LVM1-home     254:2    0 172.8G  0 lvm   /home

I would not expect any message for non-existing devices.

Best regards
