the current package in ubuntu 18.04 seems to have some bugs.
the package is missing dependency python websockify

after adding the package:
apt install python-websockify
the package seems to be missing the html dir /usr/share/xpra/www
Jun 03 18:14:57 do004466 xpra[2962]: 2018-06-03 18:14:57,250 Error: cannot find the html web root Jun 03 18:14:57 do004466 xpra[2962]: 2018-06-03 18:14:57,250 '/usr/share/xpra/www' does not exist
this might be a bug on my end because I did try switching between the beta package and the native distro package... but still seems a little messed up.

Don't use the packages provided by the Ubuntu repositories, those are always broken and dangerous in many ways, for details see wiki/Packaging/DistributionPackages.
websockify is a Recommends
dependency of our packages so it should be installed automatically.
