[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 2.02-2ubuntu8.9

---------------
grub2 (2.02-2ubuntu8.9) bionic; urgency=medium

  [ Mathieu Trudel-Lapierre ]
  * debian/default/grub.md5sum: add entry for 2.02-2ubuntu8.7; to force an
    update of /etc/default/grub back to the correct timeout value of 0 if the
    file has otherwise not been edited by the user. (LP: #1784363)

  [ Steve Langasek ]
  * debian/grub-check-signatures: Handle the case where we have unsigned
    vmlinuz and signed vmlinuz.efi.signed. (LP: #1788727)
