Failed to connect to bus: Host is down

[gsevla]

Can anyone help me with this?

Your dhclient relies on systemd to apply some settings (most likely resolver), which is not officially supported by WSL now.

It means this solution does not applies to wsl and only to linux hypervisor vm?

It only adds L2 connectivity to the VM, further setup (static IP/DHCP/IPv6/DNS/routing/etc.) is up to the user.
