L'horrible histoire du méchant ssowat et du puceau / The horrible story of the evil ssowat and the virgin

Thank you for taking the trouble to reply.
I’m not sure I follow you about using SSH. If we want self-hosting to be more popular, we have to face the fact that there are users who don’t have the training or the time to get into it.
But more importantly for me, I don’t think the problem is solved. If I understand this post correctly, this is a temporary way around the problem. And it’s not in my competence.
So how do I know I can do the updates without crashing?
