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.

Hey everyone,
Any advice on the problem below? I hit it consistently with X2Go Client, but it does not happen with the Pyhoca client.
Error:
Kex error : no match for method server host key alog: server [ssh-rsa], client [ssh-ed25519].
Client computer:
Windows 8.1 connecting to Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop.
X2Go client software v4.0.5.2. The problem does not happen with the Pyhoca software (I downloaded the latest version).
Server:
Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop.
X2Go Server: Server Core: x2goserver (4.0.1.19) x2goagent (3.5.0.31)
Server Extensions:
x2goserver-extensions (4.0.1.19)
x2goserver-xsession (4.0.1.19)X2Go Server Add-ons: x2gomatebindings (0.0.1.3)
X2Go Server Features: X2GO_CLIPBOARD_MODES X2GO_LIST_DESKTOPS X2GO_MATEBINDINGS X2GO_MOUNTDIRS X2GO_MOUNT_UNCPATHS X2GO_PUBLISHED_APPLICATIONS X2GO_RUN_EXTENSIONS X2GO_SERVERSIDE_DESKTOPCOMMANDS X2GO_SET_KEYBOARD X2GO_UMOUNTSESSION_ALL X2GO_UMOUNTSESSION_ONLYPATH X2GO_XSESSION
Additional Information:
Usually I use X2Go without ssh keys, so just type in my userid & password when connecting to the Linux desktop. This has worked fine.
When the problem above started to happen, I tried generating RSA keys on my Windows machine and transferred them to my Linux machine, but this didn't help. I also tried with DSA and also ED22519 keys, but no-go on X2Go.
I installed Pyhoca and authenticate using my userid & password. I can then connect to the suspended session that was originally created with the X2Go client.
For now I am using the Pyhoca client, but would also like to get the X2Go client working again.
Thanks!
