Hello,
I am trying to configure x2go server on a Virtual Private Server (VPS) that I rent that has Debian 10 as an operating system.
I followed the installation procedure steps on my local machine (apt install x2goclient) and on the server as root (apt install x2goserver x2goserver-xsession)
And I configured to connect via SSH automatically on port 22 in the client app.
Here is the server log (journalctl -f) when I begin the connection:

How do I fix this? My user only has a /home/myuser1 directory which I created under root and did chmod +rwx /home/myuser1.
Thank you,

Not an x2go developer, but I suggest you demonstrate that you can log in from the client machine to the server with ssh, and that you can execute remote commands:
ssh myuser1@server.domain pwd
Unless you have a key, you should be prompted for you password, and the remote side should then output "/home/myuser1" or whatever, and only that.
If you have e.g. some shenanigans in .bashrc that produce output, remote commands are likely to fail.
My user only has a /home/myuser1 directory which I created under root and did chmod +rwx /home/myuser1.
You should probably set the right owner and group as well, and remove write-bit for others. Better yet, create the user (and user directory) with adduser(8) or some other system tool.
If you plan to use ssh keys, the sshd server is rather fussy about you having the right access permission.

Hi,
some things come to mind: a) do you have xauth installed on the server system? b) try running a session with /usr/bin/xterm being the client application. This way you can rule out any problems with newer Desktop Environments. c) on the server side there should be a session log in ~/.x2go/... d) Debian 10 is EOL: https://endoflife.date/debian
