Ubuntu Roon server install tips

Help needed.

I don’t understand this section - From the Mac edit known_hosts and remove any previous entries for the server, then copy the key across. You’ll need to replace userid and hostname.

nano ~/.ssh/known_hosts
ssh-copy-id -i ~/.ssh/id_rsa.pub martin@ubuntu.home
ssh ubuntu.home

I am struggling with setting the ssh step. In my Mac terminal I used the command
nano ~/.ssh/known_hosts
and got the following.
