Question

How can I ssh access on my second computer (ubuntu)? Permission denied (publickey)

I have a ssh access via terminal on my mac working fine. Lately I got another computer (Ubuntu 20 Linux). I am trying to set up ssh access, but it just does not let me in, saying “Permission denied (publickey)”.

I added my ssh pub key (id_rsa.pub) on my local computer(Ubuntu) to the Digital Ocean (settings -> security). But, it does not fix the issue.

I also pasted the pub key in ~/.ssh/authorized_keys in the droplet.

What do I need to do to ssh access on my local ubuntu machine?

FYI: I can set password login by changing PasswordAuthentication yes in /etc/ssh/sshd_config in the droplet. However, this is not ssh access without password.

On the REMOTE server: $ sudo vim /etc/ssh/sshd_config PubkeyAuthentication yes PasswordAuthentication yes $ sudo systemctl restart sshd

On LOCAL server: $ ssh-copy-id user@remote_server_ip

On REMOTE server: $ sudo vim /etc/ssh/sshd_config PasswordAuthentication no $ sudo systemctl restart sshd

Hi there @nfujioka,

You would need to first create a new SSH key pair on your Ubuntu computer. You can follow the steps on how to do that here:

Once you have your keys ready, copy your public key and add it to your Droplet in the ~/.ssh/authorized_keys.

That way you will be able to SSH with your new key pair from your Ubuntu computer to your Droplet.

Hope that this helps! Regards, Bobby
