stderr=failed to create tun device: Operation not permitted

you probably don’t have permissions to create such device. BTW, afaik a bridge will make the vm get the traffic on the same IP, creating a separate IP for VM will probably be something else. And might require some iptables setup so your host machine relays the traffic

It seems to be working with Pronton

Install Steam client, log in and download it there. Even if you connect Lutris to you Steam account, AFAIK, the way Lutris launches those is just launching Steam

It’s not about caring. It’s about what gets done

I guess very few PR departments would agree with you
