Estas forzando usar la version 2 de ssh pero sin embargo tienes
creadas las claves privadas para la version 1 (ficheros identity y
identity.pub). No te habras confundido en algun momento? Para
asegurarte borra (o mejor mueve) del directorio .ssh los ficheros:

identity
identity.pub
id_rsa
id_rsa.pub

Vuelve a crear las llaves y vuelve a copiar la publica al server como
ya hiciste.
