I had the opposite situation in my mind. People would remove packages which are not auto removable, like ubuntu-desktop (for example because something ubuntu-desktop depends on is acting badly) and then many package in ubuntu-desktop's dependency change become auto removable: $ sudo apt-get remove ubuntu-desktop Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: a11y-profile-manager-indicator activity-log-manager adium-theme-ubuntu aisleriot app-install-data-partner apturl apturl-common baobab bluez-cups ... xorg Use 'sudo apt autoremove' to remove them. The following packages will be REMOVED: ubuntu-desktop 0 upgraded, 0 newly installed, 1 to remove and 7 not upgraded. After this operation, 46,1 kB disk space will be freed. Do you want to continue? [Y/n] It is a simpler problematic situation than the one I originally mentioned, u-u would remove software which is probably in use, no additional software is broken. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1624644 Title: By default settings unattended-upgrade is unable to automatically remove packages that become unused in conjunction with updating by other software.

This is because unattended-upgrade compares the list of unneeded packages before and after it upgrades packages to detect which packages are new unused ones. Consequently, if user installs new kernels using e.g. update-manager, the excessive kernels will not be removed by unattended-upgrade, and eventually (small) /boot will become full. Expected behavior: handle removing of unused packages differently at least until other package management software installed by default can handle removing of new unused packages.
