How and why did you install the apt-config-auto-update package? update-notifier-common is part of all Ubuntu images by default; and apt-config-auto-update has an undeclared conflict with this package.

You should remove apt-config-auto-update with 'sudo apt purge apt-config-auto-update', and then reinstall update-notifier-common.

And the update-notifier-common package should be updated to declare a Conflicts: against apt-config-auto-update.
