started xenial container, and downgraded systemd to release pocket version.
check timer units, only apt-daily is present. upgraded to apt from -updatees 1.2.24. enabled -proposed and installed unattended-upgrades from it, 0.90ubuntu0.7 two .timer units are present: apt-daily.timer random, and apt-daily- upgrade.timer between 6am and 7am. clearing /var/lib/apt/periodic $ systemctl start --no-block apt-daily.service; watch -d ls /var/cache/apt/archives/ Observed that systemd debs got downloaded in /var/cache/apt/archives. Observed that unattened-upgrades.log has entreis that it did run, but does not list that it has upgraded anything. $ tail -f /var/log/unattended-upgrades/unattended-upgrades.log & $ systemctl start --no-block apt-daily-upgrade.service 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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686470 Title: Apt updates that are uniformly spread across all timezones, with predictable application windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1686470/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
