Public bug reported:
[Impact]
Since the implementation of UEFI Secure Boot in Ubuntu, there has been a large
number of changes to the EFI patchset, handled "upstream" at
https://github.com/vathpela/grub2-fedora/tree/sb. This is a complex set of
enablement patches across a number of packages. Most of them will be fairly
straightforward backports, but there are a few known warts:
* The included patches are based on grub2 2.02~beta3; as such, some
patches require extra backporting effort of other pieces of the loader
code down to releases that do not yet include 2.02~beta3 code.
[Test Case]
The desktop, server, and alternate install images should all boot and install
on an SB-enabled system. I would recommend testing installations from both a CD
and a USB stick. After each installation, validate that Secure Boot is enabled
by checking /sys/firmware/efi/efivars/SecureBoot-*, as well as
/sys/firmware/efi/efivars/Mok* variables (for the cases where shim validation
may be disabled).
Tests should include:
- booting with Secure Boot enabled
- booting with Secure Boot enabled, but shim validation disabled
- booting with Secure Boot disabled, but still in EFI mode
[Regression Potential]
Check that non-SB installations of all these images still work. For this, it is
sufficient to test with either a CD or a USB stick, but not necessarily both.
