I have followed the instructions on the website https://learn.microsoft.com/en-us/azure/vpn-gateway/point-to-site-vpn-client-cert-linux. I have installed ubuntu on a wmware workstation version 22.04. The objective is to have Azure point to site VPN working on the VM. I have the following errors and unsure on what to do next.
