问题描述
我在 Buster 主机上安装了 Debian 10 (Buster) KVM 客户机.尝试在 Debian wiki
iptables>I've Debian 10 (Buster) KVM guest machines on a Buster host. Trying to switch to the legacy iptables on VMs following Debian wiki
update-alternatives --set iptables /usr/sbin/iptables-nft
update-alternatives --set ip6tables /usr/sbin/ip6tables-nft
update-alternatives --set arptables /usr/sbin/arptables-nft
update-alternatives --set ebtables /usr/sbin/ebtables-nft
虽然其他三个成功，但 arptables 更新失败并显示消息
While other three succeeds, arptables update fails with the message
update-alternatives: error: alternative /usr/sbin/arptables-legacy for arptables not registered; not setting
有解决办法吗?
如果您好奇，来宾机器是使用 kubeadm 启动的 Kubernetes (v1.18) 集群的节点.网络插件是 Calico.除了 MetalLB 控制器错误
If you're curious, guest machines are nodes of a Kubernetes (v1.18) cluster initiated with kubeadm. Network plugin is Calico. Everything works with default nftables settings except that MetalLB controller errors

当我从访客 VM ping 10.96.0.1 时，我得到
When I ping 10.96.0.1 from guest VM, I get

推荐答案
首先需要安装遗留包:
sudo apt-get install -y iptables arptables ebtables
然后更新替代方案:
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
sudo update-alternatives --set arptables /usr/sbin/arptables-legacy
sudo update-alternatives --set ebtables /usr/sbin/ebtables-legacy
