podman: Unable To Create Cluster Networking on Fedora 41

[adambkaplan]

What happened:

Podman provider fails to create a cluster running rootless on Fedora 41. This may only impact developers whose machines upgraded to Fedora 41 from Fedora 40 or earlier.

Note to community - this is more of a public service announcement than actual bug. Root cause is at the podman/Fedora level.

Error:

Command Output: Error: netavark: nftables error: unable to execute nft: No such file or directory (os error 2)

What you expected to happen:

KinD is able to create the cluster

How to reproduce it (as minimally and precisely as possible):

1. Upgrade host from Fedora 40 to Fedora 41 (if this happens on a clean Fedora 41 install, there is a much larger regression in Fedora).
2. Create a default cluster with kind

I see the bug was solved so I think we can close this

It seems it was some environmtal issue

Yep - was user error on my part. tl;dr don't monkey with $PATH unless you know what you are doing.
