Jarnos, I can confirm that your /etc/kernel/postinst.d/apt-auto-removal and adding the cron job resolves this problem. I installed the 4.3.0-5-generic kernel and rebooted and then manually purged the 4.3.0-1-generic and it gave some erroneous errors about not being able to find the DKMS modules to delete for that kernel. But after rebooting again there were no dkms modules and the 4.3.0-2-generic and 4.3.0-5-generic are all that are on my system.
Attached is the output of the error messages although the kernel and DKMS modules for 4.3.0-1-generic are confirmed to be gone. ** Attachment added: "output of manually deleting kernel 4.3.0-1-generic" https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1440608/+attachment/4544371/+files/kernel%204.3.0-1-generic%20removed -- 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/1440608 Title: /etc/kernel/postinst.d/apt-auto-removal wants to remove all kernels except the latest one Status in apt package in Ubuntu: Confirmed Bug description: After installing a 3rd kernel currently 3.19.0-12-generic, the /etc/apt/apt.conf.d/01autoremove-kernels file looks normal listing the 3.19.0-11-generic and 3.19.0-12-generic with 3.19.0-10-generic listed to be autoremoved. But once autoremove is completed the machine requests to be rebooted and at that time the /etc/apt/apt.conf.d /01autoremove-kernels file lists the 3.19.0-12-generic and 3.19.0-10-generic kernels. So upon rebooting the 3.19.0-11-generic is requested to be autoremoved leaving only one kernel the latest one 3.19.0-12-generic.
