While setting up WSL on my Thinkpad T480, I know I don’t normally Windows but I keep running into firmware and drivers. So I decided to switch back to Windows for a bit. While setting up WSL, I wanted to able to SSH into my laptop and run commands on it. I was able to do this by installing the WSL SSH server but I ran into a problem when trying to start the SSH server.


mmattox@a0wnhammerp01:~$ sudo /usr/sbin/service ssh start
 * Starting OpenBSD Secure Shell server sshd
 sshd: no hostkeys available -- exiting. [fail]


This error is caused by the fact that the SSH server is missing the host keys.

sudo ssh-keygen -A
sudo /usr/sbin/service ssh start

This command will generate the host keys and restart the SSH server.
