ARM 板在 22.04 上无法使用 NFS

我已经在 Ubuntu 18.04 之前很长时间在 ARM 主板上使用 NFS 挂载根目录。我在新电脑上安装了新版本 22.04，但它不再起作用了。我可以从旧主机挂载目录到新主机，但不能从 ARM 挂载目录。

以下是消息内容：

eth0: link down
IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:
      device=eth0, addr=192.168.1.6, mask=255.255.255.0, gw=255.255.255.255,
     host=192.168.1.6, domain=, nis-domain=(none),
     bootserver=255.255.255.255, rootserver=192.168.1.4, rootpath=
Looking up port of RPC 100003/2 on 192.168.1.4
eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1

Looking up port of RPC 100005/1 on 192.168.1.4
nfs: server 192.168.1.4 not responding, timed out

使用旧版本时，效果是一样的：

eth0: link down
IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:
      device=eth0, addr=192.168.1.6, mask=255.255.255.0, gw=255.255.255.255,

我遗漏了什么？谢谢。
