So it should actually work in the container if you run the command xpra
upgrade, like so:

container$ xpra start :100 # wait a few seconds for it to start
container$ xpra upgrade :100
container$ xpra list

Just starting it in a container isn't terribly useful though since that
way you can't attach to it. If you run
guix environment --ad-hoc xpra -C --share=/tmp/.X11-unix
--share=/home/$USER/.xpra

and then start the server with the above commands you should be
able to attach to it outside of the container, like:
$ xpra attach :100
$ DISPLAY=:100 gui-program # on a different terminal

Does this work for you too?

I'm not sure why the 'xpra upgrade' command seems to be required in a
container. I have no idea how to fix that.
