$ tail -f /var/log/ unattended- upgrades/ unattended- upgrades. log & upgrade. service
$ systemctl start --no-block apt-daily-
Observed that install of the packages started straight away, specially the timestamps in the -dpkg.log of the unattended upgrades.
I believe above validates that apt-daily.timer updates cache and download debs; whilst apt-daily- upgrade. timer installs the debs.
Xenial verification is complete.
