When I execute the command ssh localhost (in Ubuntu 10.10), it will display the error message "permission denied(public key)." What may be the problem?

Is there any problem in sshd_config file in /etc/ssh? Should PasswordAuthentication be set to no? I have set the PasswordAuthentication to no, but still it gives me the error "permission denied(publickey)."

Did you disable password authentication in sshd_config? Why? What you are trying to do with this? – ulidtko Apr 26 '11 at 8:47

Try

ssh-copy-id -i ~/.ssh/id_rsa.pub user@host

Or since you are on localhost try copyting your ssh key (rsa or dsa) inside a file $HOME/.ssh/authorized_keys

For key authentication in ssh you need to authorize your keys on host first AFAIK.

you need to set file permissions right , try this .. 

 $chmod go-w ~/
 $chmod 700 ~/.ssh
 $chmod 600 ~/.ssh/authorized_keys

Make sure you've installed "openssh-server" because it's not installed by default.

sudo apt-get install openssh-server

If it was not installed, OP would not get an error message at all, but hang. – Lekensteyn Apr 26 '11 at 8:52
