It seems unattended-upgrades sets default to *install* in 20auto- upgrades, (1), but in 10periodic the default for download (APT::Periodic::Download-Upgradeable-Packages) is set to just Display immediately (0)
This creates an impossible situation, Unattended-Upgrade can't install when Download is off Once the 10 file is edited to make the 20 file viable any changes in Software & Updates regarding these options is mirrored between the 2 files so they are 'on the same page' so to speak from that point on. The whole deal can be re-created at any point by removing unattended- upgrades package, then re-installing software-properties-gtk & unattended-upgrades -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1554099 Title: Changing what action for security updates unusable Status in software-properties package in Ubuntu: Confirmed Status in unattended-upgrades package in Ubuntu: Confirmed Status in software-properties source package in Xenial: Confirmed Status in unattended-upgrades source package in Xenial: Confirmed Bug description: Open software-properties.
