L'authentification par clé ne Fonctionne pas dans le serveur Ubuntu SSH

J'essaie de configurer mon serveur ssh pour une connexion sans mot de passe (connexion par clé) et cela ne fonctionne pas. J'ai essayé différentes autorisations, joué avec différents noms d'utilisateur. mêmes résultats. Il continue à me demander un mot de passe. J'ai donc activé verbose lors de la connexion et je poste la sortie ici, mais laissez-moi d'abord vous dire comment j'ai configuré 

mkdir .ssh 
ssh-keygen -t rsa -b 4096
#this created the id_rsa (private) and id_rsa.pub (public)
#then I copied the pub key over to server but first created .ssh on server
mkdir .ssh
#copy key
scp ~/.ssh/id_rsa.pub username@192.168.1.5:/home/user/.ssh

cat .ssh/id_rsa.pub >> .ssh/authorized_keys

then I changed permissions to remote .ssh dir
chmod 0700 .ssh
chmod 0600 .ssh/*

Essayez de vous connecter et demandez toujours un mot de passe... qu'est-ce qui me manque ici
