** Description changed:

  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.
