Ok. The efibootmgr command succeeded, and the efivars usage looks
reasonable, so this doesn't seem to be a problem with the nvram being filled
up.

So when you checked, you found the shim-signed package installed? I.e., the
output looked like this?

Can you confirm that /boot/efi/EFI/ubuntu/shimx64.efi is present on your
system?

If it is, you should now be able to boot Ubuntu under Secure Boot.

If it's not, you still need to install the shim-signed package after all.
