[X2Go-User] bug 106 - SSH Host Key Validation fails when ECDSA is already known

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.
