[Bug 1914279] Re: linux from security may force reboots without complete dkms modules

[Dimitri John Ledkov]

adding breaks on linux-meta in -security, on dkms package versions that
are in -updates only, would result in the kernel being held back and not
get autoinstalled.

Bug description:
  Whilst discussing

  https://discourse.ubuntu.com/t/improvements-for-hardware-support-in-
  ubuntu-desktop-installation-media/20606

  We have noticed a reference to somebody not having working backport-
  iwlwifi-dkms, whilst SRU of that happened before the v5.4 -> v5.8
  switch.

  However, kernel meta switch was pushed to security pocket, but the
  dkms modules are all in -updates only.

  This may result in people automatically installing the new kernel with
  unatanded upgrades; dkms modules failing to build; and a reboot
  required flag left on disk.

  At this point launching update manager will not offer to install dkms
  modules from updates, and will guide the users to reboot..... which
  will then cause them to boot the new kernel without the dkms modules
  that might be providing networking for them.

  Should dkms modules SRUs always getting published into -security
  pocket, as well as the -updates pocket?

  Should linux maintainer scripts prevent touching reboot required flag
  if any dkms modules fail to build?

  Should apt / unattanded-upgrades / update-manager always update dkms
  modules with kernels?
