This was a problem for me with kubuntu 21.04 as well on a MacBookPro 11,2. The workaround did the trick. Exact workaround command follows:
/boot/efi/EFI# cp -b ubuntu/grubx64.efi ubuntu/shimx64.efi /boot/efi/EFI# cp -b ubunt/grubx64.efi BOOT/BOOTX64.EFI This works immediately. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925010 Title: shim-signed 15.4 does not boot on EFI 1.10 systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1925010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
