the Debian wiki indicates that it has to be created, either by typing a
content in an editor or you can symply type as root:
# dpkg-reconfigure -plow unattended-upgrades

unattended-upgrades is not intended to be interactive (all benefit would
be lost), so it does not display anything.
if you want to observe how unattended-upgrades has run, you may examine
the content of:
/var/log/unattended-upgrades/unattended-upgrades.log
/var/log/unattended-upgrades/unattended-upgrades-dpkg.log

you do not have to run unattended-upgrades yourself: I was suggesting to
run unattended-upgrades yourself just un order to verify it runs when
called.

to work unattended, unattended-upgaded has:
- to be installed
- to be told what and how to upgrade (that is the role of
/etc/apt/apt.conf.d/50unattended-upgrades)
- to be told when to upgrade (that is the role of
/etc/apt/apt.conf.d/20auto-upgrades), else it never runs.

I would summarize it differently: installing unattended-upgrades is not
sufficient, it has to be set-up and its default setup is valid for a
reasonable goal.

For basic needs (automatic upgrades of security fixes for the stable
channel of Debian):
# apt-get install unattended-upgrades
# dpkg-reconfigure -plow unattended-upgrades
is sufficient.
If you have different or mode elaborate needs, you have to fiddle with
the set-up.

There are other ways of getting automatic upgrades, the only one I have
tested is cron-apt and I reckon unattended-upgrades is probably simpler.

NOTE: It appears that upgrade-system is a package that could interest
you: having looked quickly at it (but having never tested it), it seems
to require no set-up, just to be installed, to automatically upgrade all
packages to their newest version available (do not forget to do an
apt-get purge unattended-upgrades, it would be cleaner that way).
