==== update-notifier: 3.192.30.3 => 3.192.30.4 ====
====     update-notifier-common
  * List OEM metapackages before invoking update-manager. Before invoking
    update-manager, run a helper script to figure out if there are any
    oem-*-meta packages which apply to this system. These are enablement
    packages maintained by Canonical which install any tweaks required by a
    particular piece of hardware. The script takes care to exit quickly if
    it's been run before or if the system is already enabled. It uses
    ubuntu-drivers' python interface, so we need to add a dependency to make
    sure that is available.There will be a companion change in
    update-manager to consume this list. (LP: #1908050)
