[Bug 1925010] Re: shim-signed 15.4 does not boot on EFI 1.10 systems

[pfaelzerchen]

Sorry, to bother you. I am not sure, if this relates to this bug.

After Upgrades from 20.10 to 21.04 were enabled, I upgraded both of my
20.10 systems to 21.04. On my Intel NUC10 everything worked fine. But my
home server were not able to boot anymore. The above-mentioned
workaround (replace /EFI/Boot/BOOTX64.efi & /ef/ubuntu/shimx64.efi)
helped. The server runs now 21.04.

It is worth noting, that the server was able to boot the Ubuntu 21.04
live USB stick in UEFI mode without trouble.

The board is an older Fujitsu D3417-B with Intel Skylake. Secure boot is
disabled.

Title:
  shim-signed 15.4 does not boot on EFI 1.10 systems

Status in shim package in Ubuntu:
  Fix Released
Status in shim-signed package in Ubuntu:
  Fix Released
Status in shim source package in Xenial:
  Fix Released
Status in shim source package in Hirsute:
  Fix Released
Status in shim-signed source package in Hirsute:
  Fix Released

Bug description:
  The latest update on Hirsute made the MacBook Air from 2012
  unbootable.

  It could be recovered by booting a 20.04 live CD, downloading 20.04's
  shim package and overwriting the files in EFI/ubuntu and EFI/BOOT with
  the files shipped in the shim package.

  Machines Affected (not comprehensive):
  MacBookPro8,2
  MacBookAir5,2

  [Test case]
  For a system that has applied the workaround from https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1925010/comments/14 and is bootable:

  - install shim-signed from hirsute-proposed
  - reboot
  - verify that the system now boots without workaround

  This test case applies only to hirsute.  For all other series, there
  has been no regression, and because this is the same binary across all
  series, no other SRU testing is required.
