I am experiencing this issue even on Ubuntu 15.04 Vivid. I upgraded to kernel 3.19.0-21 today using the desktop Software Updater tool and the packages are all marked as manually installed.

This happens when updating packages with apt, aptitude, or unattended-upgrades. I'm running an up-to-date 12.04.2 LTS installed (amd64). I can see that my existing kernels were marked as automatically installed: % apt-mark showauto | grep linux-image linux-image-3.2.0-40-generic linux-image-generic And, after the update was performed by unattended-upgrades last night, the new kernel is marked manual: % apt-mark showmanual | grep linux-image linux-image-3.2.0-41-generic This is a problem, because it renders the fix in this bug, https://bugs.launchpad.net/ubuntu/+source/apt/+bug/923876 (Limit and clean-up kernel images and headers automatically in LTS) ineffective, since apt-get autoremove will not remove packages which are marked as manually installed. I'm running the following package versions: apt: 0.8.16~exp12ubuntu10.10 aptitude: 0.8.16~exp12ubuntu10.10 unattended-upgrades: 0.8.16~exp12ubuntu10.10 aptdaemon: 0.43+bzr805-0ubuntu9 This bug looks similar to https://bugs.launchpad.net/aptdaemon/+bug/1078544, however, I'm running a version of aptdaemon that supposedly has this fix applied.
