The fix is one command, <code>sudo ssh-keygen -A</code>, which creates every missing host key type. This guide shows the exact output before and after, why WSL and container images ship without keys, the other two causes that print the same line (bad permissions and a wrong <code>HostKey</code> path), and what clients see after the keys change.</p>
