The reason we depend on update-notifier is that the postinst script creates a
file inside /var/lib/update-notifier/user.d in order to notify the user that
they need to restart their virtual desktop.

At minimum, we should have "update-notifier" as "Recommends:" if we remove it
from "Depends:".  In that case, we must ensure that our postinst script runs
with exit-code 0 if update-manager isn't actually installed.

Better still: we should find out what package "xxx" is the Debian/Linux-Mint
equivalent of Ubuntu's update-manager.  Change our package so that the
notification works on those other distros as well.  Then update the Depends: to
"update-notifier | xxx".

postinst script already handles the case when this directory doesn't exist.
I don't think adding it in Recommends list is the right thing to do. From Debian
docs:
"The Recommends field should list packages that would be found together with
this one in all but unusual installations." 

I don't see why we need to worry about these update nags anyway - it's only a
way to annoy users. E.g. does Xorg or Gnome nag you to restart once they are
updated? Even linux kernel packages don't have update-manager dependency - how
is our package special?
AFAIK mintupdate which is used on mint doesn't have similar notifications
system, and even if it did, I think supporting it would be waste of time anyway.
