Summary:
You can make the necessary change to the DHCP configuration with one command:
sed -i 's|/usr/lib/dhcpcd5/dhcpcd|/usr/sbin/dhcpcd|g' /etc/systemd/system/dhcpcd.service.d/wait.conf Then reload/restart the service:
sudo systemctl daemon-reload sudo systemctl restart dhcpcd Rationale
When inspecting the /etc/systemd/system/dhcpcd.service.d/wait.conf file, as suggested by @Hannes here, I saw the path /usr/lib/dhcpcd5/dhcpcd did not exist. However, the dhcpcd executable does exist here: /usr/sbin/dhcpcd - hence the linked solution.
