LXD install: iptables-nft and iptables are in conflict. Remove iptables?

I am asked to remove iptables before installing LXD.

looking for conflicting packages...
:: iptables-nft and iptables are in conflict. Remove iptables? [y/N]

Do I remove the iptables package? Why?

Because iptables-nft provides iptables and you probably are installing something that requires iptables-nft.

Will installing the 1 iptables over the other break anything in the system?

No it won’t.
