Thanks! I tried it but I can not make it work.

I typed

$ xdg-open https://www.google.com

in a xterm window running on the remote machine, accessed via the HTML5
xpra client running in Chromium on my local PC.
Apparently nothing happened, but looking at the logs on the remote machine
I found this

2018-05-30 11:59:48,465 New unix-domain connection received on
/home/jovyan/.xpra/b58813db02a7-0
2018-05-30 11:59:48,466 Warning: remote end does not accept URLs

How can I add the open-url=yes option to the HTML5 client?

I started xpra with the following command

$ xpra start \
--daemon=no \
--bind-tcp=0.0.0.0:8888 \
--html=on \
--ssl=off \
--bandwidth-limit=500kbps \
--bell=no \
--pulseaudio=no \
--webcam=no \
--mdns=no \
--system-tray=no \
--clipboard-direction=both \
--file-transfer=yes \
--forward-xdg-open=yes \
--start=xterm \
--xvfb="Xvfb -dpi 96 -noreset -nolisten tcp +extension GLX +extension RANDR
+extension RENDER +extension Composite -screen 0 1600x900x24+32"

I run a reverse proxy with TLS termination in front of xpra.
I run xpra v2.3-r19255 since I can not install the latest version.
Whenever I try to do an "apt-get update" I get:

I tried both repositories alone, together, with http, with https...
I also tried adding the updated keys using all solutions provided here:

and here:

Any suggestion?

Thank you very much again.
