[Bug 1892754] Re: Unable to boot in UEFI+secure boot mode

[Steve Langasek]

Please either file a separate bug report for the Lenovo V130 issue, or
follow up on LP: #1886148, rather than commenting on a closed bug.

This suggests to me that this is an EFI boot entry that was manually
configured at some point in the past, rather than a firmware-provided
boot target.  And the manual configuration may not be correct for
booting Ubuntu ISOs (but perhaps it works with older images by chance).
I would want to see the output of `efibootmgr -v` from this system when
Ubuntu is booted under UEFI (but again, not on this closed bug report,
please).

  Trying to install the QA daily build for Kubuntu Groovy 20200824 -
  when booting from the USB boot media I receive the following error:

  This error occurred on 2 machines running in UEFI+secure boot mode:
