Here's what client I'm using:

/Applications/Xpra.app/Contents/Helpers/Xpra --version
xpra v1.0.1-r14723

Hi John,

This Docker script builds 14.04 and installs the xpra server end which goes with it.
I am guessing you are trying to connect with a 16.04 flavour of Ubuntu or a version of xpra which is a little bit newer than the server end build of xpra.

I suspect you can issue some switches at this stage (to make it backwards compatible with the other end)
xpra --ssh="ssh -p 22" attach ssh:[email protected]:10

The cure of me was to swap:

FROM ubuntu:14.04
for
FROM ubuntu:16.04

And remove
RUN ln -s /usr/bin/Xorg /usr/bin/X

in the Dockerfile which is no longer necessary.

I am personally playing with the script so the Docker container runs in an Amazon AMI in instance and I have added vncviewer at the end of this line.

RUN apt-get install -y libreoffice-base firefox libreoffice-gtk libreoffice-calc xterm vncviewer

Then once in you can run a tweaked version of lines like this
ssh [email protected]
./docker-desktop -s 1440x858 -d 10
./docker-desktop -s 1024x768 -d 10
./docker-desktop -s 1680x1000 -d 10

Connect via xpra --ssh="ssh -p 22" attach ssh:[email protected]:10
IMMEDIATELY paste the password as soon as you see it in the gibberish!!!!!

Run this from the desktop of the remote
vncviewer -listen 0

########################

Then at the client pushing end on a typical linux 16.04 box

x11vnc -connect x.x.x.x:5500

Cheers Mark

PS On a sad note, looking at the xpra page:

Should I use the version shipped with my Linux distribution? 
It depends, generally not. 

Now I'm currently strugging with the stable version that comes on 16.04 - just errors and drops connection but I've gone from work to home. Single screen to dual screen.

Basically it's getting foggier

I'm actually trying to connect with xpra on macOS.
