I can confirm the /efi directory is back, although with different capitalization than before:
Focal: /EFI /EFI/BOOT /EFI/BOOT/BOOTx64.EFI /EFI/BOOT/grubx64.efi /EFI/BOOT/mmx64.efi Groovy: /efi/ /efi/boot /efi/boot/bootx64.efi /efi/boot/grubx64.efi /efi/boot/mmx64.efi This is a bit annoying from the static validation point of view, but can be worked around. I can't spot what change caused the /efi directory to be included again in the ISO filesystem. Does anybody have a pointer? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895131 Title: Groovy Desktop *BREAKS* the most common method of creating UEFI bootable drives for Ubuntu installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1895131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
