Cannot spin up a HTML mode

[netikras]

xpra start :10 --start-child=xeyes --bind-tcp=0.0.0.0:10000 --html=on --no-daemon

At first I was getting

2019-11-22 10:37:13,840 cannot create group socket '/run/xpra/netikras-PC-10'
2019-11-22 10:37:13,840  [Errno 13] Permission denied
2019-11-22 10:37:13,891 pointer device emulation using XTest

I ran sudo chmod o+w /run/xpra to get around this. Not sure if I did it right, but I no longer see the Permission Denied error.

But I'm still getting an error below when trying to either do xdg-open ​http://127.0.0.1:10000/ or attach via https://xpra.org/html5/connect.html .

Attaching a full log.

Am I doing something wrong?

xpra --version: xpra v4.0-r24461

pip show websockify | grep -i vers
Version: 0.9.0

cannot create group socket

See wiki/FAQ

Error: cannot find the html web root
 '/usr/share/xpra/www' does not exist

Which xpra package did you install?
This directory must exist, that is the html5 client.

pip show websockify | grep -i vers

Websockify is not required or used by xpra since v2.4: #2121.

Thanks Antoine for the hint!

though I feel stupid now :) All I needed it the obvious thing: apt install xpra-html5. Somehow I was under impression that the html5 client comes OOTB with the xpra package. After reading wiki/Clients/HTML5 I did not even think I'd need to install smth else :)

Anyways, my bad. Thanks again!
I'm very glad you folks are doing this project. It's exactly what I've been looking for for a while now. TA!

Somehow I was under impression that the html5 client comes OOTB with the xpra package

It is a Recommends dependency of the main xpra package.
So you must have used --no-install-recommends when you installed xpra.

I have updated the wiki page: wiki/Clients/HTML5 (removed websockify, etc)

Note for those hitting the same error but not using the official xpra packages: most distributions packages should NOT be used and they often miss crucial functionality, such as the HTML5 client.
