[Bug 1925010] Please test proposed package

[Łukasz Zemczak]

Hello Balint, or anyone else affected,

Accepted shim-signed into hirsute-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/shim-
signed/1.47 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 on 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, what testing has been
performed on the package and change the tag from verification-needed-
hirsute to verification-done-hirsute. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-hirsute. In either case, without details of your
testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

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 Hirsute:
  Fix Committed
Status in shim-signed source package in Hirsute:
  Fix Committed

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.
