This is fine that you see this error. To stop seeing this error, please comment out the following line in your /etc/ssh/sshd_config file:

HostKey /etc/ssh/ssh_host_ed25519_key

According to this bug post it may indicate something went wrong with your openssh server install. I had this issue on a ubuntu box and a simple sudo apt-get install openssh-server --reinstall recreated the missing keys under /etc/ssh/ and resolved the issue.
