UFW não foi possível determinar a versão do iptables

Estou construindo uma plataforma Linux embarcada personalizada baseada no NXP i.MX8 com Yocto. Quero usar o UFW para configurar o firewall. Quando inicializo o sistema e tento usar o UFW ele retorna um erro

Não foi possível determinar a versão do iptables.

Eu tenho os pacotes iptables e nftables instalados. Tentei alterar manualmente o link simbólico do itpables para apontar para o binário iptables-legacy. Ainda falha. Como posso consertar isso? Por favor, veja as versões abaixo.

    root@iot-gate-imx8plus:~# iptables -v
    iptables v1.8.7 (legacy): no command specified
    Try `iptables -h' or 'iptables --help' for more information.
    root@iot-gate-imx8plus:~# nft -v
    nftables v1.0.2 (Lester Gooch)
    root@iot-gate-imx8plus:~# ufw version
    ufw 0.36.2

UPDATE:

Strace pointed out the problem. UFW makes an assumption of where the iptables binary is and Yocto installed it somewhere else:
