Comment 9 for bug 1925265

The remaining packages marked for removal result from oem-config-remove-gtk, which doesn't simply call apt-get purge - it uses aptdaemon.

And aptdaemon looks to me like it's supposed to remove "obsoleted dependencies" (equivalent of apt-get autoremove) via worker.aptworker.AptWorker.commit_packages -> worker.aptworker.AptWorker._check_obsoleted_dependencies. So I think this is now actually an aptdaemon bug?
