Hi, I have a problem with xpra, which used to work fine until the last update some days ago.

Client version: xpra v5.0-r0 (Ubuntu 20.04)
Server version: xpra v5.0-r0 (Fedora 37)

Now if I run on the client

$ xpra start ssh://myserver/myport

the program exits with this output:

What is myport? Is it a number? Why obfuscate it?

Try running with -d ssh and posting the output.

Thank you for your reply;

What is myport? Is it a number? Why obfuscate it?

yes, sorry, my fault

Try running with -d ssh and posting the output.

My guess is that the session failed to start.
Try to run xpra start --no-daemon on myserver directly (ie: in an ssh terminal session).
Does that run or fail?

That's expected.

Can you try this now instead:
xpra _proxy_start :999
It should start a server then terminate the connection if you press enter and complain that you're not an xpra client.. because you're not.

This also looks fine..
Maybe clean all the log files and the session directory, and then try again using the xpra client - perhaps the server log file will show something different in that case.

ok, just to be sure: would it be ok rm -rf /run/user/1000/xpra/* on the server?
Many thanks

And make sure that all xpra processes are terminated.
Ideally also the Xorg processes associated with these servers.

ok I cleaned all files and also restarted the whole server, sorry which command should I run? On the client or on the server? thanks

which command should I run

From your client:
xpra -d ssh start ssh://myserver/999

Then if it still fails, look in your server log.

invalid packet encoding: 'rencodeplus' decoder is not available

Something is wrong with your installation.
rencodeplus must be enabled in v5.

You can use xpra showconfig and xpra showsetting packet-encoders to find out why it is not.
My guess is a stray configuration file.

ok so I found:

$ xpra showconfig |grep packet-encoders
packet-encoders       (used)   = 'rencode', 'bencode', 'yaml'      <class 'list'>
packet-encoders      (default) = 'rencodeplus', 'rencode', 'bencode', 'yaml'  <class 'tuple'>

$ xpra showsetting packet-encoders
* default config:
packet-encoders     : 'all'                                    (<class 'list'>)

Can /usr/local/etc/xpra be the faulty one? Can I remove it? Is there anything else I need to do?
Thank you for your patience

/usr/local/etc/xpra does not belong to the xpra packages. You must have installed it yourself.
It should be totally safe to remove it.
Make sure to remove everything xpra related from /usr/local.

Thank you very much! Changing /etc/xpra/conf.d/55_server_x11.conf as per #2764 (comment) made it working.

@angus73 this is only a temporary solution and is not a supported configuration.
Your problem with Xorg crashing is normally solved by applying system updates and / or rebooting.
