Can we set up Passwordless SSH in Ubuntu (18.04) without root privileges? Is there any way to access files in /etc directory without root permissions? (I need to be able to set up Passwordless SSH between non-root users from between a local and remote system, but I don't have the root privileges on either system)

    It is not clear what you are asking. Do you have an account in the remote computer you want to ssh into? Can you use ssh with password? Please edit your question and add more information about your setup. – user68186 Feb 20 '19 at 20:45

  • Assuming ssh is "properly" setup by whoever has root privileges, You can setup password less login for yourself. This question How can I set up password less ssh login? has been already answered. – user68186 Feb 21 '19 at 18:12

If your ssh server already has the publickey authentication method enabled, all you need to do is to append your own public key to the .ssh/authorized_keys file in the home directory of your server user. No further administrative configuration required for that.

And configuration files in /etc are normally all owned by the root user and not writable by anyone else, you can not bypass that as regular user without sudo. Otherwise that would be a security threat.
