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:
https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2
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
