I updated from the PPA last week and noticed the html5 client no longer works. I just get an empty white screen instead of windows loading. I was able to fix this by copying the /usr/share/xpra/www folder from a system that had a prior working install on it.
A hint may be here:
Files www.broken/connect.html and www/connect.html differ Only in www.broken: connect.html.br Only in www.broken: connect.html.gz Common subdirectories: www.broken/css and www/css Only in www.broken: favicon.ico.br Only in www.broken: favicon.ico.gz Files www.broken/favicon.png and www/favicon.png differ Common subdirectories: www.broken/icons and www/icons Files www.broken/index.html and www/index.html differ Only in www.broken: index.html.br Only in www.broken: index.html.gz Common subdirectories: www.broken/js and www/js
Just tested and could not reproduce any problems whatsoever with both the 2.1 (stable) version and 2.2 beta.
Please see wiki/ReportingBugs, in particular in your case: the browser, etc.. Maybe also the javascript console output, server log, etc.
You may also want to see if deleting all the ".gz" and ".br" files helps. Those are optional anyway.
This is with Google Chrome Version 60.0.3112.90 and Safari 10.1.2 on OSX 10.12.6 Sierra.
I'm able to reproduce on two xenial systems (Linux Mint) when upgrading from PPA.
Javascript console output shows errors with the broken code:

Looks like the problem is with the jquery.js. The problem may be in /usr/share/xpra/www/js/lib where jquery.js is linked to a non-existing file on these new installs:
lrwxrwxrwx 1 root root 39 Aug 7 14:32 jquery.js -> ../../../../javascript/jquery/jquery.js
placing a copy of jquery.js directly in the /usr/share/xpra/www/js/lib folder seems to fix things.
libjs-jquery
is a recommended package when you install xpra and should have been installed automatically.
You must have changed your default apt system configuration or used a special installation command to ignore this dependency and that's why you're missing this file. Don't do that.
You should mention that in your bug reports in the future as per wiki/ReportingBugs to save everyone some time.
Correct. libjs-jquery is indeed a recommended package as I can see from "apt-get show xpra". It does *not* install by default on the (now) three Linux Mint systems I have tried this on because the default is to not install recommended packages. I don't know if this is correct behavior for the distribution, but it is what it is.
I'm documenting this here in case it is helpful to others.
From /etc/apt/apt.conf.d/00recommends:
APT::Install-Recommends "false";
So, libjs-jquery will *not* install as a recommended package. Perhaps it should be a dependency to ensure it will be installed since it is required.
