[Bug 1862171] Re: [SRU] shim 15+1552672080.a4a1fbe-0ubuntu2

[Łukasz Zemczak]

Along with the shim-signed SRUs, I have also accepted the related shim
binary syncs (15+1552672080.a4a1fbe-0ubuntu2). Since those did not have
any relevant bug links (as they're syncs from one build), they did not
appear as part of this SRU - but they are.

Bug description:
  [Impact]
  New shim, various upstream fixes, fixes support for ARM64, also see bionic arm64 SRU bug: LP: #1890813.

  [Test case]

  Roughly

  https://wiki.ubuntu.com/UEFI/SecureBoot/ShimUpdateProcess/TestPlan

  but I certainly don't have any clue about the maas one.

  [Regression potential]
  - System might not boot anymore
  - System might not boot some helpers like fwupd anymore (which was a regression in ubuntu1 we fixed)
  - New security bugs that make shim load unsigned stuff are of course possible too
