Package: x2gothinclient-displaymanager In X2Go TCE setups, X2Go Client always starts with option --add-to-known-hosts. Thus, the host key of a remote server X2Go Server gets never verified by the end user. A proper solution would be to provide SSH known_hosts keys of known X2Go Servers inside a TCE/chroot system-wide known_hosts file.
