Bought an OVH and got given user ubuntu etc? Here's how to fix that issue.

• Type sudo nano /etc/ssh/sshd_config
• Scroll Down until you see #PermitRootLogin prohibit-password change that to PermitRootLogin yes then Save.
• Type sudo passwd your_password - Enter New Password, then again.
• Once that is done do service sshd restart
• Then login using user root and password your_password

Hope it works for you.
