start shadow session on client

You mean on server, right? What is the command used?

version 6.0-r0 Xpra Server Version v3.1

This is out of date - probably won't work.

2024-06-13 13:25:39,085 SSH EOF on stderr of run-xpra

Try adding -d ssh to your client to see the full ssh events.

But really, this is not supposed to work, see https://github.com/Xpra-org/xpra/wiki/Versions

thomas725 commented 4 months ago

Thanks for the explanations! Yes I meant start shadow on server.

I figured I need to update the servers xpra version. Is there a debian repository I can put into a /etc/apt/sources.list.d/xpra.list file? Or do I need to download a *.deb package and install it manually?

The output with -d ssh:

xpra -d ssh attach ssh://server-hostname/0
