Cannot SSH access to Debian cloud image 9.1.1:

[AJNOURI]

I provisioned a Debian instance with a keypair:
nova boot --key-name mykey1 ...
chmod 600 mykey1.pem

192.168.0.191 being the floating IP:

ssh -i mykey1.pem debian@192.168.0.191

Enter passphrase for key 'mykey1.pem':
debian@192.168.0.191's password:
Permission denied, please try again.
debian@192.168.0.191's password:
Permission denied, please try again.
debian@192.168.0.191's password:
Permission denied (publickey,password).

It is asking for passphrase of the keypair, which is empty, then it asks foor the password for the user debian?

Same process works fine with Ubuntu xenial image:

[root@devstack1 ~(keystone_admin)]#ssh -i mykey2.pem ubuntu@192.168.0.191
