Package: debian-ports-archive-keyring Version: 2017.12.30 Severity: normal Upgrading from 2016.11.28 left the obsolete conffile /etc/apt/trusted.gpg.d/debian-ports-archive-2016.gpg on my system. It seems you forgot to update debian-ports-archive-keyring.maintscript when moving the 2016 key to the removed keyring.
