So, this might partially be a linux-meta/overrides bug. The top-level metas (linux-$flavour) should be in the metapackages section so that if they're removed (for instance, by someone who doesn't want headers, but kinda likes kernels), the manually installed bit is transferred down one level to linux-image-$flavour and linux-headers-$flavour.
It might also be valid to say that the neverautoremove apt/kernel magic could/should include the mid-level metas in the list, so they're just considered manual regardless of what state they were accidentally put in. -- 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/1787460 Title: Unattended upgrades removed linux-image-generic Status in unattended-upgrades package in Ubuntu: New Bug description: On a fairly fresh install of 18.04 with no modifications whatsoever to the unattended-upgrades configuration, it decided to remove linux- image-generic which also removed linux-modules-extra which caused sound drivers to disappear, etc. The relative snippet from /var/log/unattended-upgrades/unattended- upgrades.log is: 2018-08-15 06:18:00,048 INFO Starting unattended upgrades script 2018-08-15 06:18:00,048 INFO Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, o=UbuntuESM,a=bionic 2018-08-15 06:18:01,552 INFO Removing unused kernel packages: linux-headers-generic linux-image-generic linux-headers-4.15.0-32-generic linux-headers-4.15.0-32 2018-08-15 06:18:01,588 WARNING Keeping auto-removable linux-headers-generic package(s) because it would also remove the following packages which should be kept in this step: libxml2 linux-image-4.15.0-32-generic linux-modules-4.15.0-32-generic linux-modules-extra-4.15.0-32-generic 2018-08-15 06:18:09,476 INFO Packages that were successfully auto-removed: linux-headers-4.15.0-32 linux-headers-4.15.0-32-generic linux-headers-generic linux-image-generic 2018-08-15 06:18:09,477 INFO Packages that are kept back: linux-headers-generic 2018-08-15 06:18:10,300 INFO Packages that will be upgraded: libxml2 linux-image-generic 2018-08-15 06:18:10,300 INFO Writing dpkg log to /var/log/unattended-upgrades/unattended-upgrades-dpkg.log 2018-08-15 06:18:39,238 INFO All upgrades installed 2018-08-15 06:18:42,818 INFO Packages that were successfully auto-removed: linux-image-generic linux-modules-extra-4.15.0-32-generic 2018-08-15 06:18:42,818 INFO Packages that are kept back: ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: unattended-upgrades 1.1ubuntu1.18.04.5 ProcVersionSignature: Ubuntu 4.15.0-32.35-generic 4.15.18 Uname: Linux 4.15.0-32-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.9-0ubuntu7.3 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Thu Aug 16 13:17:30 2018 InstallationDate: Installed on 2018-07-24 (23 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180724) PackageArchitecture: all ProcEnviron: TERM=xterm PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: unattended-upgrades UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1787460/+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
