After the recent xpra update to 4.1.1 the Xpra HTML5 Client was gone. I manually installed it from https://github.com/Xpra-org/xpra-html5 and python3 ./setup.py install /usr/local/share/xpra/www This should be included in the port, again.
Right, HTML5 client is in its own repo now, so this would require creating another port. Right now xpra-html5 have no releases nor tags, so I bugged upstream with this problem.
