SSH Error: no hostkeys available

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin Nano

Hi all,

Very excited to have successfully set up an OS on my Jetson Orin Nano.

However, I can’t seem to SSH into the device over USB or WiFi. This also means my SDK Manager can’t install SDK components.

On my host computer, with USB connected, I can ping 192.168.55.1 successfully. I know it’s the Jetson, because when I unplug it, the ping fails. All SSH commands result in a “connection refused” message.

Onboard the Jetson, it seems that the ssh.service consistently fails to start. When checking the logs, I notice the error “sshd no hostkeys available”.

I’ve checked where the hostkey files should be on Ubuntu, and they are in the proper place. So idk why this would be.

Any help would be really appreciated - thanks!

Hi,
This look to be duplicate of topic 324849 and please make sure you have done this:

I rewrote because I figured this was a better wording. But yeah, I have a user set up done.

In the end, reflashing the whole system worked :)
