I created an Ubuntu core SD for my Raspberry-3 and booted it. Then from my IPad using an app I tried to SSH to it. As far as I understood from the instructions I should not be asked any password to login. But I am being asked a password:
root@Ubuntu-1:~# ssh email@example.com The authenticity of host '192.168.1.7 (192.168.1.7)' can't be established. ECDSA key fingerprint is SHA256:yfOBN1/EPQ8v6b1+n6QFCAj/+tyruioord Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.1.7' (ECDSA) to the list of known hosts. Rpi@192.168.1.7's password: Permission denied, please try again.
If I can access to RPi I can set a password for local access, but I cannot, since I do not know what ethis password is. How can I resolve this puzzle and access my newly created Ubuntu running RPi?
