You need to change the sshd config file in the remote server  probably in  etc ssh sshd config    Change  PasswordAuthentication no   to   PasswordAuthentication yes   And then restart the sshd daemon

The server first tries to authenticate you by public key  That doesn t work  I guess you haven t set one up   so it then falls back to  keyboard-interactive   It should then ask you for a password  which presumably you re not getting right  Did you see a password prompt

You may want to double check the authorized keys file permissions     chmod 600    ssh authorized keys   Newer SSH server versions are very picky on this respect

[permissions] Permission denied (publickey,keyboard-interactive)
