How do I remove the host key?
This bug is quite annoying. Especially because it's easy to trigger and the prompt dialog doesn't explaint how to remove the existing key. http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=106
I already tried 'ssh-keygen -R [host]' with no effect. and according to the bug report this is not how it's done anymore...

For me, removing the key with 'ssh-keygen -R' works fine to make x2goclient stop complaining. When x2goclient adds a host-key for me, it adds to ~/.ssh/known_hosts. Have you made sure you removed all versions of the hostname? If your server is called server.domain.tld, be sure to remove both 'server' and 'server.domain.tld' with 'ssh-keygen -R'. Alternatively you can delete ~/.ssh/known_hosts, which will mean having to re-accept host-keys for all other hosts you normally ssh into.

Anyway this bug is triggered by doing a ssh to the machine before using the x2goclient. Not an unnormal pattern. Essentially this error is a false positive and hinting the user what needs to be done would be a good idea.
