We are unable to solve the below error in Ubuntu16.04: 

Permission denied (publickey,password).

We have tried this Ubuntu Handbook guide.

What else can we try?

  • Now, maybe you enable firewall in server, so you can disable firewall or allow port ssh in firewall with command: " sudo ufw disabe " or " sudo ufw allow from any to any port 22 " – Kotler Aug 21 '17 at 10:04
  • We have tried both the commands, but remains same error: Permission denied (publickey,password). – shivashankar m Aug 21 '17 at 10:10

Follows the below steps: By default, the SSH server denies password-based login for root. In /etc/ssh/sshd_config, change:

PermitRootLogin without-password

to

PermitRootLogin yes

And restart SSH:

sudo service ssh restart
