This is a conffile belonging to the isc-dhcp-server package. If this line
was missing, presumably you had a modified /etc/apparmor.d/usr.sbin.dhcpd
file before upgrade, and kept your version on upgrade rather than installing
the version from the new package. Do you have an
/etc/apparmor.d/usr.sbin.dhcpd.dpkg-dist file alongside it? You might want
to see what differences there are between those two files, and replace your
modified profile with the stock one so that you don't run into upgrade
problems in the future.
