Description Guido 2021-04-12 20:25:38 UTC

Description of problem:

Upgrade grub2 "installs" (puts expected files in proper locations), but I get this error:

"/usr/sbin/grub2-install: error: this utility cannot be used for EFI platforms because it does not support UEFI Secure Boot."

I tried various settings in BIOS. It only boots UEFI, Secure Boot on/off is irrelevant.

Downgrade to 2.04 & all is restored.

RPMs used: grub2-common grub2-efi-x64-* grub2-tools-*

Version-Release number of selected component (if applicable):

2.06~rc1

How reproducible:

Every attempt

Actual results:

grub2-install says

"/usr/sbin/grub2-install: error: this utility cannot be used for EFI platforms because it does not support UEFI Secure Boot."

Expected results:

An installation with no errors that boots

Additional info:

Lenovo X390 running F33.

Please resolve before releasing F34!

You shouldn't use grub2-install on EFI installs, the grub2-efi-x64 package
installs the grub2x64.efi binary in the correct location. The command does
not work correctly and causes the GRUB installation to not support Secure
Boot anymore (you might not want use it but others users do).

Yes, indeed. Thanks.

As an aside, is this new in 2.06? I have used grub2-install utility manually for many years on 2.04 or earlier on Fedora & other distros without issue, ever. On EFI or BIOS, no problems.
