An annoyance about this change is that it reuses the apt-daily.timer for only download and lets the upgrade be triggered by a new apt-daily- upgrade.timer.
Systems using apt <1.2.24 which were sensitive to the upgrade point of time would typically have overridden the apt-daily.timer to happen at a fixed time. After upgrade to apt 1.2.24 those systems would still have apt-daily.timer run at the time chosen by the administrator but triggering /usr/lib/apt/apt.systemd.daily update to download packages would make it bail out (as the unattended-upgrades 0.90-ubuntu0.7 which introduced the --download-only option is not a SRU). But upgrades, and effectively also download until a manual upgrade of unattended-upgrades, would happen at the default apt-daily-upgrade.timer time (06:00+random(60m)). Security updates that warps carefully scheduled and important system events like this leaves the impression that administrators are not in control of their machines. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
