This is odd. Karl's suggestion won't help, as this is not related to kex algorithms.

Instead, your server provides an RSA host key, but the client (in this case
libssh for X2Go Client) seems to support ssh-ed25519 only.

Odd, because libssh certainly does support RSA keys. Did you generate the server
host keys yourself? Maybe it's too big?

libssh definitely supports RSA keys and it should report that its list as well.

You're not seeing this issue with PyHoca, because PyHoca uses Paramiko, an
implementation of SSH in python. The supported features differ based upon the
implementation, as you can see (libssh vs. Paramiko in this case.)
