So yes, it's possible that this was only a candidate for autoremoval
/after/ the previous run of update-manager had finished.

Title:
  kernel from bionic did not get autoremoved by either unattended-
  upgrades or update-manager

Status in unattended-upgrades package in Ubuntu:
  New
Status in update-manager package in Ubuntu:
  New

Bug description:
  I happened to run apt manually on my system this morning to remove a
  package, and I was informed:

  The following packages were automatically installed and are no longer required:
    linux-image-4.15.0-36-generic linux-modules-4.15.0-36-generic
    linux-modules-extra-4.15.0-36-generic

  This was surprising, since I have run update-manager yesterday (with
  no intervening reboot), and unattended-upgrades is enabled, and both
  of those packages should have already removed this stale kernel before
  now.

  After apt autoremove, my current installed packages are:

  $ dpkg -l linux-image'*' | grep ^ii
  ii  linux-image-4.18.0-10-generic          4.18.0-10.11 amd64        Signed kernel image generic
  ii  linux-image-4.18.0-11-generic          4.18.0-11.12 amd64        Signed kernel image generic
  ii  linux-image-generic                    4.18.0.11.12 amd64        Generic Linux kernel image
