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

[sudodus]

I tried again in the Lenovo V130, and this second time the internal UEFI
system is upgraded so that it no longer allows booting (not even when
the current daily Lubuntu Groovy iso file is used to create a persistent
live drive with mkusb (with the setting 'upefi', using 'usb-pack-efi').
So the bugfix against the boothole seems to have entered this computer
during the first session.
