For some time now I can no longer log in to my raspberry pi server via ssh:

I have no idea what this could be and I could not find anything helpful on the internet about the error message. I am using Xubuntu Linux and I have no idea what further details to add to be able to submit this question.
Edit: The problem must be with the Raspi, when I try to log in from another PC, the same error message comes up.
