@Tyler Hicks (tyhicks) : I didn't upgrade, it is a fresh install. (Checksum of installation image is verified.)
I compared the file that I own at: "/etc/apt/apt.conf.d/50unattended-upgrades" with the file that you attached: https://launchpadlibrarian.net/295870733/50unattended-upgrades using the known 'diff' command and found that the two files are identical. I probably didn't notice the 2-3 lines which didn't include '//' at their beginning. My discomfort is with the postponed update for the security patches (it seems that they aren't installed immediately as they available). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1645115 Title: Auto update frequency isn't proper Status in unattended-upgrades package in Ubuntu: Incomplete Bug description: With Ubuntu 16.04: I suspect that security updates aren't installed immediately: The file "/var/log/apt/history.log" shows that "/usr/bin/unattended-upgrade" is executed every 2-3 days. By reading the "Software Updater" app/GUI I see that there are security updates available which weren't installed. In "Software & Updates", under the "Updates" tab: The field "When there are security updates: " is set to the value "Download and install automatically". Also all checkboxes at the top (below "Install updates from: ") are checked (with a V ). Note that the file "/etc/apt/apt.conf.d/50unattended-upgrades" contains only comments (lines starting with "//").
