secure boot disabled

Wednesday, 31 January 2018

I installed Fed 27 on a Dell XPS 13 9370 using Fed 27 Live
on a usb stick after deleting Ubuntu 16.04 LTS that came
installed on the device.

I checked that secure boot + necessary conditions were
set to 'enabled' in UEFI.

However after install I find 'secure boot disabled'.
$ dmesg | grep -i secure
[    0.000000] secureboot: Secure boot disabled
[    5.630671] Loaded UEFI:MokListRT cert 'Fedora Secure Boot CA:
fde32599c2d61db1bf5807335d7b20e4cd963b42' linked to secondary sys
keyring
$ ls -l /sys/firmware/efi/efivars/Secure*

/sys/firmware/efi/efivars/SecureBoot-8be4df61-93ca-11d2-aa0d-
00e098032b8c

Can this have anything to do with the fact that this notebook
only has Thunderbolt 3 and USB 3.1 (C) ports so that I had to use
an adapter cable ?

As I did not expect this I did not check what happened under Ubuntu.

(Aside from some probably neglectable ACPI hiccups everything else
 seems to be working OK).
