If it helps, I have in my notes the full output of `efibootmgr -v` from Oct 16 with the 'ubuntu' entry missing, and then the full output after I ran grub-install to recover.
I do not have a full output of `efibootmgr -v` from earlier, but I do have just the `ubuntu` entry from February, after a little misadventure with creating UEFI-bootable USB drives messed up my EFI boot vars and I successfully recovered by running `grub-install`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900121 Title: firmware upgrades remove the ubuntu boot loader from EFI boot vars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupd/+bug/1900121/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
