Description Solene 2021-07-01 16:34:44 UTC
When running xpra, it creates a log file with this content

2021-07-01 18:33:00,517 Error: cannot enable SSH socket upgrades:
2021-07-01 18:33:00,517  No module named 'paramiko'
2021-07-01 18:33:00,518 cannot access python uinput module:
2021-07-01 18:33:00,518  No module named 'uinput'

paramiko error can be fixed by installing dev-python/paramiko but uinput doesn't seem to be in portage.

I've not been able to run xpra
Comment 1 James Le Cuirot gentoo-dev 2021-07-06 21:49:33 UTC
Which xpra version was this?

Although I think something should be done here, both of these dependencies are optional and xpra should function without them.

I don't know exactly what uinput provides but the FAQ literally says you can ignore that error and xpra has worked perfectly well for me without it.

xpra is supposed to use Paramiko by default but fall back to plain OpenSSH otherwise. I don't use it over SSH and happen to have Paramiko installed anyway so I cannot confirm this but my guess is you were unable to get it working for other reasons.
Comment 2 Solene 2021-07-06 21:54:39 UTC
hi, thanks for looking into this.

I use xpra 4.2 with USE="client clipboard cups dbus ffmpeg jpeg lz4 opengl pulseaudio -brotli% -csc -doc% -ibus% -lzo -minimal% -pillow -pinentry% -server -sound -test -vpx -webcam -webp"

I'm trying it by ssh-ing into my gentoo system and running "xpra start" then I get this output

Entering daemon mode; any further errors will be reported to:
  /run/user/1000/xpra/S9797.log

maybe I'm doing it wrong?
Comment 3 James Le Cuirot gentoo-dev 2021-07-06 22:05:10 UTC
You need to have xpra installed on both the client and server, but you don't need to SSH to the server side before starting xpra. It does that for you. From the client side:

xpra start ssh://USERNAME@HOST/ --start-child=xterm

See https://github.com/Xpra-org/xpra/blob/master/docs/Usage/README.md for more examples. If you're still having trouble, join #xpra on irc.libera.chat.

I did that and the xpra output from the initiating server was giving a path to an xpra log (on the gentoo side where xpra should launch programs) which contains

Do you have the server USE flag enabled on the server side? That pulls in x11-base/xorg-server[-minimal,xvfb] as a dependency but it looks like you don't have that.
Comment 6 Solene 2021-07-19 10:33:47 UTC
Indeed, I didn't build xpra with server USE, I recompiled it with "server" added to the USE list and I'm going a bit further.

I can start a program in xpra and expose it on TCP and I'm able to attach to it using my xpra client. I use this command line: "xpra start -start=xterm --bind-tcp=0.0.0.0:8789"

I can't run/attach to xpra using "xpra start ssh://solene@my-server/ --start-child=xterm", I see the process is getting spawned on the server but I can't access it. The GUI is displaying "Connecting to server" for some time before doing a timeout.

Also, on the server, if I use "xpra list{,-sessions,-windows}" the output is that nothing is running.

I tried to use the xpra ssh command locally from the gentoo computer, and it doesn't attach either.

Here is the logs of: [1] backend programs getting spawned by ssh [2] xpra using ssh locally

Hi Solene,

The Error messages of Xpra is confusing. Xpra has many optional features that emits "Error:" to the console but is non-fatel. 

The important things are those with backtraces. See below.

See below.

No an Error.  No html? Fine, we are using ssh or tcp.

No an Error either.

Not an Error.  Who needs xdg menu?  I don't know what it is.  Xpra cannot parse it, fine.

Not an Error.  Xpra wants to use paramiko in vain when there is openssh, and falls back to openssh.  No need to care.

Bingo! This is the very bug after a long list of noise and false "Error" prompts.

dev-python/pillow needs to have USE=webp enabled.

If that fixes your issue, we should let xpra[webp] depend on dev-python/pillow[webp].

Cheers,
Benda

    x11-wm/xpra: Conditionally require pillow[webp] and drop pillow USE flag
    
    We have had pillow as an unconditional dependency for ages. It is technically
    optional, but upstream strongly recommends it.
