SSH без пароля - я чувствую, что перепробовал все

Question

Мне кажется, что я попробовал более десятка разных способов сделать это очень простое задание, но я все еще не могу заставить работать SSH без пароля между моими компьютерами. Один компьютер - Dell Optiplex 755 (Linux NODE-DELL755 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux). Другой - Raspberry Pi3 (Linux NODE-RPI3 4.9.35-v7+ #1014 SMP пт. 30 июня 14:47:43 BST 2017 armv7l GNU/Linux).

Вот вывод из моей попытки ssh: `` `
