It's in an arch specific RPM. e.g. grub2-efi-x64-2.04-31.fc34.x86_64.rpm contains grubx64.efi created and signed within the Fedora build system. The grub2-install created executable is not signed, will not work with UEFI Secure Boot enabled unless manually signed by the user, and it has different behavior from the Fedora created one: where it expects to find modules and the grub.cfg. > But the correct invocation for EFI systems is different.

No the correct invocation is "dnf reinstall grub2-efi-x64 shim-x64" Suggesting UEFI users install GRUB with grub2-install is asking for a support nightmare, it's untenable. -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
