Ubuntu 18.04 In system journal I see these error messages appear every 1 to 5 minutes.
error: Could not load host key: /etc/ssh/ssh_host_ecdsa_key
error: Could not load host key: /etc/ssh/ssh_host_ed25519_key
See screenshot
These lines are commented in sshd_config:
#HostKey /etc/ssh/ssh_host_ecdsa_key
#HostKey /etc/ssh/ssh_host_ed25519_key
I connect via SSH without entering password using rsa key with no problems
What are these error messages about then and how to fix it?
