rbalint, in the output there is some oddity: "Keeping auto-removable linux-image-extra-4.8.0-54-generic package(s) because it would also remove the following packages which should be kept in this step: libpam-systemd libsystemd0 libudev1 systemd systemd-sysv udev (Reading database ... 53554 files and directories currently installed.) Removing linux-image-extra-4.8.0-54-generic (4.8.0-54.57~16.04.1) ..."
So it says it is keeping linux-image-extra-4.8.0-54-generic and right thereafter it is removing the same package. ** Summary changed: - By default settings unattended-upgrade does not automatically remove packages that become unused in conjunction with updating by other software + By default settings unattended-upgrade does not automatically remove kernel packages that become unused in conjunction with updating by other software -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624644 Title: By default settings unattended-upgrade does not automatically remove kernel packages that become unused in conjunction with updating by other software To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1624644/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
