I have updated my jackal robot from ubuntu 14.04 to 16.04 so that I could upgrade to ros kinetic, but now upon booting the jackal when I try to ssh to it as I normally have in the past I get a message saying:

ssh: connect to host 192.168.94.106 port 22: Connection refused

I am not sure how to fix this

Sounds like there's no SSH server running on your jackal. You'll have to install that.

Sorry, I should have mentioned in the question. I am able to ssh into it using an ethernet cable (using the directions in jackals documentation about setting up its network), and after this I am able to ssh into jackal normally (ssh administrator@192.168.94.106 )

However, after rebooting Jackal, I cannot do ssh administrator@192.168.94.106 because I get the aforementioned error. However after sshing using the ethernet connection I am then able to ssh normally again, so my issue is not being able to ssh normally after reboot

Then this sounds like a configuration issue specific to jackal, and perhaps something to contact CP about -- if you're not comfortable with solving that yourself.

It's also not really a ROS problem, although you're using a ROS-enabled robot.

Btw: please add all relevant information to your question next time. You'll save everyone time.
