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!
