Last night I wrote a recent Ubuntu daily image to thumb-drive and tried to boot it on

sony vaio svp112a1cw (i5-9400u, 4gb, intel haswell-ULT)
which now has secure boot on and it failed with

"ERROR
Verification failed: (0x1A) Security Violation"

Today I've upgrade ISO and now it's 2020-08-28 and thus reported on iso.qa.ubuntu.com.

It was written two ways to media
- `dus` or mkusb
- gnome-disks restore image

Both times it fails on the sony vaio crapbook with listed error.
The thumb-drive media booted both times (`dus` or gnome-disks) on other non-secure-UEFI boxes

Disable secure-boot on sony ultracrap and Ubuntu groovy will boot. The ISO won't boot with secure-boot enabled.
