Public bug reported:
I have a system that runs unattended-upgrades just fine. Now i want to
automate removal of old kernels and kernel header packages that are
accumulating otherwise. So i set 'Unattended-Upgrade::Remove-Unused-
Dependencies "true";'. But it doesn't work.

Note that the majority of these packages have been installed by
unattended-upgrades from precise-security.
According to the comments within/etc/apt/apt.conf.d/50unattended-
upgrades, this should automate autoremoval:
// Do automatic removal of new unused dependencies after the upgrade
// (equivalent to apt-get autoremove)
Unattended-Upgrade::Remove-Unused-Dependencies "true";
but nothing happens (note the line "Packages that are auto removed: ''
":
$ unattended-upgrades --debug --dry-run
