However, on my 17.10 system, I currently have 3 kernels marked for retention while the kernel I have booted is the newest of these. This means that I'm not able to upgrade to 18.04 without manual intervention, because I have a /boot that's sized just large enough to fit 3 kernels, not 4, apt autoremove won't remove any of the kernels. The sequence here is that I was running 4.13.0-36-generic; I updated, which pulled 4.13.0-37-generic onto the system; I ran apt autoremove --purge, which removed any kernels older than -36- from the system; I did *not* reboot; I installed 4.13.0-38-generic (from artful- proposed); all three kernels present are now marked for retention. I rebooted, and all three kernels are still marked for retention. If /etc/kernel/postinst.d/apt-auto-removal were run *now*, it would mark 4.13.0-36-generic as autoremovable. But there is nothing that reruns this script on boot. Maybe there should be? $ last vorlon tty2 :0 Tue Mar 20 11:14 still logged in reboot system boot 4.13.0-38-generi Tue Mar 20 10:34 still running vorlon tty2 :0 Tue Mar 6 23:12 - down (13+10:21) reboot system boot 4.13.0-36-generi Tue Mar 6 23:10 - 10:33 (13+10:23) wtmp begins Tue Mar 6 23:09:27 2018 $ ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: apt 1.5.1 ProcVersionSignature: Ubuntu 4.13.0-38.43-generic 4.13.16 Uname: Linux 4.13.0-38-generic x86_64 NonfreeKernelModules: zfs zunicode zavl zcommon znvpair ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Mar 21 13:02:43 2018 InstallationDate: Installed on 2010-09-24 (2735 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) SourcePackage: apt UpgradeStatus: Upgraded to artful on 2018-03-21 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1757529/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
