Bug#1127652: closed by Steve McIntyre <steve at einval.com> (Re: Bug#1127652: grub-efi-amd64-signed: Booting grub is impossible on 2.14 version with "failed to install protocols" and "cannot load image" errors)

[horsey_guy]

Apologies for the rushed bug report.

When I experienced these errors, I have installed grub2.14 (upgrading `grub-efi-amd64-unsigned`, `grub-efi-amd64-signed`, `grub2-common`, `grub-common`, & `grub-efi-amd64-bin`) from the Debian Sid repositories, which are already signed. Grub was not self-built nor self-signed.

What's peculiar is that I tried upgrading to grub2.14 again from the Debian repositories (executing `grub-install` and `update-grub` again), but the same error messages occurred on the second attempt.

Downgrading to grub2.12 works as normal.

So please reopen this bug report as I believe this could be a legitimate bug with grub2.14.
