It seems unlikely that the EFI System Partitition was not properly mounted. I booted successfully a couple dozen times before the grub 1.99-21ubuntu3.7 update. Moreover the EFI System Partition contains an EFI/ubuntu/grubx64.efi file that shows a timestamp corresponding to the grub 1.99-21ubuntu3.7 update. That would have been difficult to achieve if the EFI System Partition was not properly mounted at the time of the update.
This appers more likely to be some kind of path problem, since the system WILL boot successfully when the grubx64.efi is explicitly chosen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098952 Title: grub_efi_secure_boot symbol not found after update to grub 1.99-21ubuntu3.7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1098952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
