[Bug 1644541] [NEW] Update stuck at “configuring unattended-upgrades”

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

On basically fresh install from ubuntu-16.04.1-desktop-amd64.iso; no
updates or installs had been applied since installing the OS from the
media.

During execution of "Software Updater", it freezes indefinitely while
"Installing updates..." at the step marked "Configuring unattended-
upgrades."

It appears that this happens if System Settings->Software &
Updates->Updates, "Automatically check for updates" has been set to
"Never."

If that is instead set to "Daily" and the following are then set in
/etc/apt/apt.conf.d/10periodic then the update succeeds:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";

Someone else had asked about this issue at AskUbuntu.  Their question
along with my answer (from Kevin) provide some further details:
