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 > lisi@Eros:~$ su > Password: > root@Eros:/home/lisi# unattended-upgrades > root@Eros:/home/lisi# > > What has that done?

It took a long while doing it, but appears to have dome > nothing. 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 > If I have to run it myself, then it isn't working. The whole point, from my > point of view, is for it to work unattended. 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 have clearly completely misunderstood what unattended-upgrades is intended > to do.

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).
