No. You can have x86_64 CPU but the firmware is 32-bit, hence ia32 which is why there is: grub2-efi-ia32-1:2.02-81.fc30.x86_64.rpm The user space will still be 64-bit but the EFI binaries will be 32-bit for the rare firmware floating out there that require it. There isn't a problem with 32-bit and 64-bit EFI binaries being located on the same EFI system volume in EFI/fedora, the firmware figures it out (I think by filenaming convention which is mentioned in the UEFI spec). My suggested change for this section: 🔗 Install the bootloader files If you don't already have the relevant packages installed, do for Fedora 22 and later versions with DNF or with YUM for older Fedora releases: - dnf install grub2-efi shim + dnf install grub2-efi-ia32 grub2-efi-x64 - yum install grub2-efi shim If you do, then try: dnf reinstall grub2-efi shim - yum reinstall grub2-efi shim --- I think it's a negative for user to have to read a wall of text explaining any aspect of architecture to them. It's bad enough we have to explain BIOS vs UEFI. Just tell them to install the bootloader for both, which is what a default Workstation installation does anyway. And then remove deprecated yum command. For reinstall, the existing command will replace both packages and their respective EFI binaries. > but I believe I only need the 'grub2-efi-x64.x86_64'. > Given that, maybe the anaconda installation should be checked to not > pull uneeded packages? I'm pretty sure UEFI bitness is exposed by /sys/firmware/efi/fw_platform_size but I don't know if anaconda uses it. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
