Public bug reported:
When doing certification testing of Ubuntu 16.04 on a Lenovo x3550 M5,
we've found a Secure Boot failure. After installing via MAAS with Secure
Boot DISABLED, we've enabled Secure Boot. The following appears on the
screen (SOL session):
No key pressed. Preparing to boot normally...
>>Start PXE over IPv4.
Station IP address is 10.1.10.17
Server IP address is 10.1.10.1
NBP filename is bootx64.efi

/HD(15,800,100000,ae01bc523f0af546,2,2)/File(\efi\ubuntu)/File(shimx64.efi)/EndEntire
error: cannot load image.
Press any key to continue...
Pressing a key at this point produces a GRUB menu containing nothing but
a "Local" option. Selecting that option causes a return of the "Booting
local disk..." message and failure.
Disabling Secure Boot produces the same sequence, except that "error:
cannot load image" does NOT appear, a GRUB menu with an "Ubuntu" option
appears briefly, and the system boots normally.
Note that Secure Boot DOES work normally in a MAAS environment on other
computers, such as Cisco C220 M4 and C240 M4 and an Intel NUC
DC53427HYE. (The NUC, however, required a firmware update to work with
Secure Boot active.)
This may well be a firmware bug, but I'm reporting it against Shim
because it could be it's a Shim bug that's interacting with the firmware
or there may be something Shim can do to work around the problem.
