I'm also still seeing this on 16.04 LTS with systemd. This is an upgrade, not a fresh install.

The syslog says: dhcpd: Can't create new lease file: Permission denied It looks like a permission problem, because # chown -R dhcpd:dhcpd /var/lib/dhcp the above command temporarily solves the issue, until dhcpd is restarted: at that time, the ownership of the directory and the lease file is set back to root:root.
