This may or may not be an issue, but here are my observations. The order of operations seems to be the cause of my issue with the additional factor that the /boot partition size is unusually small compared to recent Ubuntu installations.
Order of operations as follows: 1. unattended-install script is run 2. removes packages found in /etc/kernel/postinst.d/apt-auto-removal 3. Installs new kernel 4. creates new /etc/kernel/postinst.d/apt-auto-removal At this point it does not remove any old packages after the new kernel is installed. However, when unattended-install is run a second time it will remove those packages. This seems like an awkward approach. Ideally, the old kernel packages would get removed the first run of unattended-install. I considered safety concerns in removing older kernels after an update but then it still gets removed on a second run. It is also there is a setting here that I overlooked. I applied a work around in kernel/postinst.d/zzz_autoremove to simply run apt-get autoremove -y a few seconds after unattended-install is completed. This approach is not ideal but functional for this potentially unique issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1267059 Title: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work Status in unattended-upgrades package in Ubuntu: Fix Released Status in unattended-upgrades source package in Precise: Fix Released Status in unattended-upgrades source package in Trusty: Fix Released Bug description: I have a system that runs unattended-upgrades just fine.
