Netlink send error : Invalid argument

I am trying to build and run vsome IP basic examples on Ubuntu 20.05 in Widnows 10 as WSL. I follow the procedure describe in vsomeip in 10 minutes. I am following Availability section where one service is offered and client notifies if available.

The output at service side is

`2021-06-07 18:08:37.073496 [warning] Netlink send error : Invalid argument

It does not able to detect network interface which should have been loopback, 'lo'. It is detecting as 'n/a'. Client does not know any service.

Same issue is reported here but it is closed without any solution

How can I solve this issue?

The network confguration as well as the vsomeip configuration are needed to help here. However, does WSL support netlink at all?

Have you managed to resolve this? I am facing the same issue.

I solved it I am not sure but I think issue was, I was using WSL V1 i.e. it was not complete Kernel. I shifted to WSL V2 which is complete OS. That solved the issue. In case, that does not fix your issue, drop message here, I will look into my code.

Thanks! Finally, I got it up n running!
