Your copy of /etc/init.d/nut-server should have the following lines:

# Check if /var/run/nut exists and has the correct perms
check_var_directory() {
  [ ! -d ${pid_dir} ] && mkdir -p ${pid_dir} \
    && chown root:nut ${pid_dir} \
    && chmod 770 ${pid_dir} \
    && [ -x /sbin/restorecon ] && /sbin/restorecon ${pid_dir}
}

This works on my Ubuntu 16.04 test system. I am using a PPA with some libusb-1.0 changes, but this particular file does not seem to have changed since Ubuntu 14.04 (looks like there is some systemd emulation of SysV-style init scripts for NUT on 16.04). Are you using systemd or upstart?
