conf.d/50unattended-upgrades has stable and security uncommented in the Unattended-Upgrade::Allowed-Origins section. Does that take precedence over, say, 10periodic? Or is the kernel not part of the Download-Upgradeable-Packages clause (set to "0")?
And nothing shows for the kernel this month at all in history.log or term.log.But apticron did send me a mail about it, with a list of legitimate looking fixes and urgency set high, claiming dann frazier was in charge of the upgrade.l
