Install legacy iptables binaries for Ubuntu/Debian by 0xC45 · Pull Request #18625 · kubernetes/website

0xC45 · 2020-01-11T17:23:26Z

On the latest Debian 10, the arptables-legacy and ebtables-legacy binaries are not installed by default. Although the (non-legacy) versions are installed by default, it appears the respective packages that provide the legacy binaries must be installed in order to switch to the legacy alternatives. If you attempt to switch to the legacy alternatives without installing the arptables and ebtables packages, you will see an error:

update-alternatives: error: alternative /usr/sbin/arptables-legacy for arptables not registered; not setting

I have confirmed that the packages are present on Debian 10 and Ubuntu 19.10 and they provide the legacy alternatives. See:

@steadysupply Did you find a solution to this problem for Ubuntu 18.04, since Ubuntu doesn't provide alternatives like /usr/sbin/iptables-legacy?
