[Bug 876910] Re: When starting open ssh server without host keys in /etc/ssh/, the keys are not automatically generated.

[Clint Byrum]

Hi Jon, sshd is no longer started and/or stopped with /etc/init.d/ssh
unless you are running inside a chroot.

The host keys are typically generated in the postinstall script of
openssh-server. You can find the copy that should be used for this at
/var/lib/dpkg/info/openssh-server.postinst. So if you don't have keys,
its likely that something went wrong during that process. Try this to
remedy the situation.

sudo apt-get install openssh-server --reinstall

Marking Incomplete pending response.
