odroid-c2 : cannot ssh with 'PasswordAuthentication no'

[hatahata50]

Hi all .

i install archlinux_xfce-20160415-longsleep-pine64-4GB.img .
and
i set in /etc/ssh/sshd_config
PasswordAuthentication no

then
i cannot access the odroid-c2 PC by ssh.

namely
ssh -l foge 192.168.100.101
Permission denied (publickey).

all lines of /etc/ssh/sshd_config is next .
AuthorizedKeysFile .ssh/authorized_keys
PasswordAuthentication no
ChallengeResponseAuthentication no
UsePAM yes
PrintMotd no # pam does that
Subsystem sftp /usr/lib/ssh/sftp-server

PasswordAuthentication ssh is no ploblem .

by the way
i frequently use vnc over ssh at internet .
so 'PasswordAuthentication no' is needed .

ssh -l foge 192.168.100.101 -L 5900:localhost:5900
and then
on another terminal
xtightvncviewer localhost:5900

"archlinux_xfce-20160415-longsleep-pine64-4GB.img"

... I am amazed that would work at all on the C2. But, we don't support that at all, so install from the official instructions.
