For what it's worth, it seems it might be HOW the script is being called. Testing the apt-auto-removal script here (Kubuntu 15.04) with kernels 3.19.0-29-generic, 3.19.0-30-generic, and 3.19.0-31-generic installed and after a reboot to load -31:
1) Noticed the call to autoremove 3.19.0-30-generic. 2) Read /etc/apt/apt.conf.d/01autoremovekernels and saw -29 and -31 listed as "NeverAutoRemove" 3) Manually removed 3.19.0-29-generic. 4) Ran "sudo /etc/kernel/postinst.d/apt-auto-removal" 5) Re-read /etc/apt/apt.conf.d/01autoremovekernels and saw only -31 listed as "NeverAutoRemove" 6) Ran "sudo /etc/kernel/postinst.d/apt-auto-removal 3.19.0-31-generic" 7) Re-read /etc/apt/apt.conf.d/01autoremovekernels and saw -30 and -31 listed as "NeverAutoRemove" So it worked when called properly in that case. I thought it possible that part of the problem is it's being called with the wrong kernel version. I re-installed -25 and -21 along with -30 and -31. This resulted in -25 and -31 in the never remove list. But again: When apt-auto-removal is re-run with -31, the never remove list changes to -30 and -31. -- 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.
