Original GitHub issue: https://github.com/netbirdio/netbird/issues/1761

Describe the problem

After updating the Linux Netbird Client via the AUR repository from version 0.26.3-1 to version 0.26.4-1, the client cannot connect to the network anymore.
Running any netbird related command simply returns the following error message: Error: status failed: init route manager: setup routing: add rule v6 netbird: add routing rule: address family not supported by protocol

To Reproduce

Steps to reproduce the behavior:

Update netbird client to version 0.26.4-1 on linux
Run sudo netbird service start from command line

Expected behavior

I expected the client to connect to the existing network, but no such luck.

Are you using NetBird Cloud?

I am currently self-hosting the NetBird control panel on an AWS instance.

NetBird version

Installed version is 0.26.4

NetBird status -d output:

As with any other command, at the moment the output is just an error message: Error: status failed: init route manager: setup routing: add rule v6 netbird: add routing rule: address family not supported by protocol

Additional context

In an attempt to make the debugging process easier, I have enabled the debug logs. Here is the file resulting from simply starting the netbird client via systemd: client.log
It should be noted that no messages are being written to either the nebird.out or netbird.err files.
