> if we do want to support secure boot on bionic

Yes, this is non-negotiable.  In fact, publication of the updated shim
to bionic has been held up because of concerns over regressing fwupd-
signed, which exists specifically *for* support under SecureBoot.

So, I'm going to mark this verification-failed since the sbat section is
missing.

Please upload a fixed fwupd package with sbat support ASAP so that we
can land the updated shim.

** Changed in: fwupd-signed (Ubuntu Focal)

Bug description:
  [Impact]
  Future releases of shim will require that EFI binaries that are chainloaded include an SBAT region.  fwupd in bionic does not currently contain this region.

  [Test Case]
  Verify that a shim that checks for sbat region can boot the fwupd with sbat region.

  [Regression Potential]
  This is moving to a new stable release in each of the series which is in bug fix only mode.  The sbat region is the only "feature" that has been backported to this series in over a year.
