We'll eventually get a retry support in apt, if updating failed, but
there are no plans to react to connection state changes.

The retry will be linear every 10 minutes or so I suppose, but can't be
sure, we'll have to see - I'd do exponential, but systemd does not give
us an option for that.

Any change is not suitable for backporting to old releases.

Tthis is a tough topic, but our behavior wrt to updating is not
different from other major platforms - e.g. Android only installs
updates in the same conditions. It just gets the service triggered
automatically if it missed it due to conditions, but systemd does not
retrigger nor does it know about network state.

FWIW, I believe that all desktops do have their own integration, because
they need to for every other distribution, because that's how PackageKit

Bug description:
  For many if not most laptop computers, Unattended Upgrades seems all
  but useless by design.

  For upgrades to happen, with default config, 3 conditions must be met:

  - an internet connection must be up and running when the timer or cron or 
anacron tries the unattended upgrade
  - the connection must not be metered, whatever that means 
(Skip-Updates-On-Metered-Connections "true")
  - the computer must be plugged in (OnlyOnACPower "true")

  These are insurmountable problems for many laptops on the go.
  Inevitably, security upgrades will almost never run unattended on such
  computers. I discovered with shock that Unattended Upgrades had almost
  never run on my laptop. I tried all possible config tweaks. Nothing
  worked reliably and in the end I gave up and wrote a upgrade script
  which uses Network Manager's connection-up hook. Unattended Upgrades
  needs to do something like this out of the box. Users should not need
  to write scripts to ensure security upgrades.

  Unattended upgrades is an excellent project for servers. But it really
  needs to work, out of the box, on laptops too.
