And yes, unattended-upgrades are enabled in the configuration:
10periodic :
APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "0"; APT::Periodic::AutocleanInterval "0";
20auto-upgrades :
APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Unattended-Upgrade "1";
So why is unattended-upgrades not installing any upgrades?
Requested extras:
ls -l /var/lib/apt/periodic:

This is the entireity of /var/log/unattended-upgrades-dpkg.log:

All three of those entries are from me running "sudo unattended-upgrades --dry-run" manually.
The previous unattended-upgrades-dpkg.log.1.gz contains this:
Log started: 2017-10-03 11:18:26 ^MExtract templates from packages: 36%^MExtract templates from packages: 72%^MExtract templates from packages: 100% Preconfiguring packages ... dpkg: error: dpkg status database is locked by another process Log ended: 2017-10-03 11:18:27
Note that this computer gets rebooted every day. Previous log unattended-upgrades-dpkg.log.2.gz is quite long and actually shows stuff being installed. It ends with this:
