/etc/hosts is not changed on Ubuntu 22

[Koshmaar]

Hello, I'm unable to get kubefwd to work on Ubuntu 22. The problem is that /etc/hosts is not changed:

 $ sudo kubefwd svc -n api -v

The services are running on minikube 1.33, and I can easily port forward using kubectl port-forward.

The hosts file is very basic, there is almost nothing here, no special syntax or whatever. Attaching just in case:

127.0.0.1	localhost

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

The only similar problems I saw on internet, were on Windows: #268 , and even there the error was visible, while here kubefwd doesn't error in any way, continues to run in background, but doesn't actually forward.

Does anyone have any ideas on what might be the problem? Or what to try for debugging it?
