I installed X2Go yesterday on a Ubuntu server of mine. Of course I didn’t get my configuration right the first time 🙂 but X2Go was working 😉 . Since it was a VPS I just re-installed from scratch. However, I wasn’t able to get my X2Go windows client to work after the re-install. I received something similar to the error below.
Hostkey for server changed. The host key is now xx xx xx xx
The connection is being closed now.
After doing some Google searches I finally found something that kind of helped. They recommend deleting the “.ssh” directory but that didn’t work for me. I had to delete the “known_hosts” file under the directory “C:\Users\XXXX\ssh”, XXXX of course being your username.
You can also edit the file and just delete the line that contains the IP address your trying to connect to.
I am running Windows 7 Professional.
