freshly install xpra error following example

[kirk]

I just installed xpra on a remote server followed the example on the website:

Executed the below command on the server

xpra start ssh:hostname --start=xterm

Getting the following error:

That command is meant to be used on the client, not the server. It requires a display for the client to run.

If your client is headless or if you don't want to connect immediately, you can use "--attach=no".
