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.
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..."
