Title:
  grub-install fails due to uninitialized variable

Status in efivar package in Ubuntu:
  Fix Released
Status in efivar source package in Focal:
  Fix Released

Bug description:
  [Impact]
  grub-install can fail, either by segfaulting or reporting an Internal Error.

  [Test Case]
  The issue is due to an uninitialized variable, so reproducing it is somewhat unpredictable (depends what randomness is in memory). However, a user seems to have a reliable reproduction setup as reported in LP: #1904226.

  [Fix]
  This upstream patch fixes it:
  https://github.com/rhboot/efivar/commit/5dc12cc56c79d293cf68d12a0b84373a785745e7

  [Where problems could occur]
  Most likely a problem with this fix would have little to do with the fix itself (which is simple/obvious), so I'll just state the usual issues/problems that can occur with upgrading packages (e.g. disk too full to unpack, etc).
