Hi Karl, Thank you for your response! I took your example but it didn't work for me: I edited /etc/ssh/sshd_config on the server and restarted ssh, but X2GO still complained with the same kex error, but Pyhoca is still OK. I'll take a closer read and will try it again soon; maybe I messed up somehwere.

Hello - Here is a link with some background, which describes two workarounds :
http://permalink.gmane.org/gmane.linux.terminal-server.x2go.user/2368
You would add this to your sshd_config file on the client (Linux) machine, then restart ssh
# KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
I hope this helps.

The catch is that everything below the "# KexAlgorithms" line needs to be *on one line*.
E-Mail clients usually wrap the line somewhere in the middle and insert a newline character, so when you copy-paste it from E-Mail, it will add 3 lines instead of 2, which will confuse the heck out of sshd instead of fixing the issue.
E.g. in my E-Mail client, there's a line wrap at "diffie-hellman-group-exchange-". Make sure it says "diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1...", not "diffie-hellman-group-exchange- sha256,diffie-hellman-group14-sha1..."
