update-alternatives：错误：未注册的arptables的/ usr / sbin / arptables-legacy；没有设置 [英] update-alternatives: error: alternative /usr/sbin/arptables-legacy for arptables not registered; not setting

问题描述

我在Buster主机上安装了Debian 10（Buster）KVM客户机。尝试在遵循 Debian Wiki <的VM上切换到旧版 iptables / a>

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

其他三项成功的同时， arptables 更新失败，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

是否有解决方法？

如果您感到好奇，则来宾计算机是使用kubeadm启动的Kubernetes（v1.18）集群的节点。网络插件是 Calico 。除 MetalLB 控制器错误外，所有内容均使用默认的 nftables 设置

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

何时我从来宾VM ping 10.96.0.1 ，我得到

When I ping 10.96.0.1 from guest VM, I get

PING 10.96.0.1 (10.96.0.1) 56(84) bytes of data.

推荐答案

首先，您需要安装旧版软件包：

At first you need to install legacy packages:

sudo apt-get install -y iptables arptables ebtables

然后更新替代方法：

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
