[Bug 1974223] [NEW] FTBFS since changes in apt for automatic kernel removal

[Olivier Gayot]

Public bug reported:

Since the following changes in apt have landed in focal-updates and
bionic-updates, unattended-upgrades FTBFS on both series:

  * Revert "Protect currently running kernel at run-time"
  * Backport Determine autoremovable kernels at run-time (LP: #1615381) as of
    2.4.5; including the change to only protect two kernels, not last installed
    one (LP: #1968154)
