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

[sudodus]

Thanks, this bug is squashed :-)

I can confirm that a USB drive cloned from the current daily Lubuntu iso
file boots in UEFI mode with secure boot in my Dell Precision M4800.

(This computer can also boot in UEFI mode without secure boot and in
BIOS mode with the current daily Lubuntu iso file.)

The old problem that a Lenovo V130 in UEFI mode with secure boot fails
is still there and independent of the bug reported here.
