[Bug 1376693] [NEW] update-notifier not showing updates

[bog]

Public bug reported:

update-notifier is not working any more on our 14.04 machines (about 150).
It is not showing available updates and not showing stuff from user.d
This is what i get from debugging:

```
update-notifier --debug-inotify --debug-hooks --debug-misc --debug-uevent 
** (update-notifier:5751): DEBUG: trayapplet_create()
(update-notifier:5751): hooks-DEBUG: init_already_seen_hooks

** (update-notifier:5751): DEBUG: tray_applet_ui_destroy: hook-notifier
** (update-notifier:5751): DEBUG: trayapplet_create()
** (update-notifier:5751): DEBUG: crashreport_check

```

If i run the same with --force i get at least an icon for installing updates.
I tried touching the relevant files like:
sudo touch /var/lib/update-notifier/dpkg-run-stamp
and 
sudo touch /var/lib/update-notifier/user.d/bla-java8-repo
but this doesent help either.

Any Suggestions?

Why is it that update-notifier sees all the Hooks a not relevant?
How do i ensure that a Hook is relevant?

P.S:

Just for the record, we have no avahi running.
