[winswitch] [xpra] xpra-html how to

[yonatan zaken]

Hi,

xpra v4.3-r40
Ubuntu 18.04.6 LTS

I cloned xpra-html5 to my home directory and installed as mentioned:
https://github.com/Xpra-org/xpra-html5

And I run the following in terminal:
xpra start --start=xterm --bind-tcp=127.0.0.1:10000
Standard output shows:
=================================================
Entering daemon mode; any further errors will be reported to:
  /run/user/1000/xpra/S23615.log
Actual display used: :2
Actual log file name is now: /run/user/1000/xpra/:2.log
=================================================

Then I run in terminal:
xdg-open http://localhost:10000
And a chrome window opens with the following:
==================================================
Server Error

Error code 400.

Message: this port does not support HTTP requests.

Error code explanation: 400 = Bad request syntax or unsupported method.
==================================================

This is my log output:
Quite hard to follow,
*Is it the uinput missing module that might cause the issue?*
*There is a line mentioning "install the html-xpra package" even though
it's installed.*
*Any suggestions how to proceed?*
