Error Permission denied (publickey) when I try to ssh
This error appears when trying to SSH into a server. The publickey in the
brackets after the error message is misleading. One reason might be wrong
configuration in sshd_config file and the second reason might be insufficient
permissions of the authorized_keys file.

To enable the password authentication, follow these steps:
- Log in as a root to your system
- Edit the contents of the
/etc/ssh/sshd_configfile using the text editor:
sudo nano /etc/ssh/sshd_config
- Find the
PasswordAuthenticationoption in the file and change its value toyesso it looks like this:
# Change to no to disable tunnelled clear text passwords
PasswordAuthentication yes
- Save the file and exit the editor. Then run the following command to apply the changes:
sudo service sshd reload
