Right. apport wouldn't know to grab U-U logs for an apt bug. Attached. Also below is the journal snippet that lead me to conclude that system unit updates were responsible:

It attempted to upgrade apt apt-transport-https apt-utils firefox firefox-locale-en flashplugin-installer libapt-inst2.0 libapt-pkg5.0 libgme0 but the unattended-upgrades-dpkg.log log terminates after apt is configured. I had to dpkg --configure --pending and apt-get -f install to get apt back into working order. There were no errors, crashes or cores logged. The journal indicates that apt-daily.service stopped and restarted around the time of the upgrade, so I am assuming that is the problem (that systemd killed the update session as the result of an update to the unit files) --- ApportVersion: 2.20.3-0ubuntu8 Architecture: amd64 CurrentDesktop: XFCE DistroRelease: Ubuntu 16.10 InstallationDate: Installed on 2016-12-06 (7 days ago) InstallationMedia: Ubuntu 16.10 "Yakkety Yak" - Release amd64 (20161012.2) NonfreeKernelModules: openafs Package: apt 1.3.2ubuntu0.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.8.0-30.32-generic 4.8.6 Tags: yakkety Uname: Linux 4.8.0-30-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1649959/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
