Today while trying to start ssh server on my WSL Ubuntu installation, I got this error:
sshd: no hostkeys available -- exiting

After searching on the web, I found that the solution was really simple, at least in this case.
I only needed to run:
sudo ssh-keygen -A

Then, start/restart the ssh service:
sudo service ssh start
sudo service ssh restart
