How long should I wait for an answer to my question https://askubuntu.com/questions/1131817/18-04-2-authentication-error
on here, and in the meantime is there anything I can do to make it more answerable?   

I've already included a fair bit of detail so afraid adding more might overwhelm potential responders and discourage them,  but would very much welcome dialogue about editing my question if that might help.

  Thanks,     +  John
