[Bug 1463869] [NEW] 15.0.4 on xps 13 9343 does not boot with uefi secureboot

[gobble]

Public bug reported:

I just wiped off Windows 8  from my new Dell XPS 13 9343 and did a clean
install of Ubuntu 15.0.4. It did not boot in UEFI secure mode. I had to
disable secureboot to boot Ubuntu. Not sure if this is because Dell has
not embedded the  CA cert  signed by Microsoft in this machine and used
to sign the  first-stage UEFI bootloader/shim or if  its actually a
problem that can be fixed by using another key to sign the shim? DELL
does supply a developer edition of XPS 13 with Ubuntu and perhaps they
use a bootloader with different keys than whats in the standard shim?
Let me know if I should open a ticket with DELL instead or if you can
check the DELL version of Ubuntu about what keys they have used and
supply that in the default shim?

Apologies if the problem description is inaccurate or confusing due to
some incorrect assumption. Feel free to correct my understanding of it.
