[Phillip Susi]

This was not fixed in grub2-signed: it still does not produce a 32 bit
signed package, only the amd64 one.  This prevents the signed stub from
being installed on a 32 bit EFI system, as in bug #1644915.

[Adam Conrad]

Hello Shih-Yuan, or anyone else affected,

Accepted grub2-signed into trusty-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/grub2-signed/1.34.13 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Bug 1591818] Re: Add support for running a 64-bit Linux kernel on a 32-bit EFI.

[Shih-Yuan Lee]

** Description changed:

  [Impact]
  
  * Some platforms only have 32-bit EFI BIOS. When executing `grub-
  install` on them, it will make the system can not boot up again because
  of the wrong GRUB EFI payload and UEFI boot entry.
  
  [Test Case]
  
  * Executing `grub-install` on a 32-bit EFI platform should appear the
  following results.
  
- $ sudo grub-install 
+ $ sudo grub-install
  Installing for i386-efi platform.
  Installation finished. No error reported.
  
  $ sudo efibootmgr -v

  * Executing `grub-install` on a 64-bit EFI platform should appear the
  following results.

 or \EFI\ubuntu\grubx64.efi if there is no grub-efi-amd64-signed installed.
  
  [Regression Potential]
  
  * This patch is directly backported from Ubuntu 16.04 so it should be OK
  without any regression.
  
  [Other Info]
  
  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> 
About Ubuntu
  Ubuntu 14.04
  
  2) The version of the package you are using, via 'apt-cache policy pkgname' 
or by checking in Software Center
  grub2 2.02~beta2-9ubuntu1.8
  
  3) What you expected to happen
  Executing `grub-install` will install platform files by i386-efi on 32-bit 
UEFI BIOS.
  
  4) What happened instead
  It installed platform files by x86_64-efi instead.
  
  P.S. Ubuntu 16.04 doesn't have this issue.

Please add a test case so that this can be verified. Particulary, please
add some analysis about regression potential, as boot loader induced
changes are highly sensitive to causing fatal regressions.
