Hah, sorry!

apt-get clean;apt-get update;apt-get install xpra
(or apt-get upgrade)

Long answer: I made a mistake building the latest release twice
It was just a bigger blooper than I realized: the next release will
support many more Debian and Ubuntu distribution versions thanks to the
use of private ffmpeg libraries (just like we already do for RPMs), see:
So I ended up building 0.17.5 instead of the beta for Trusty, and you
ended up with a dead link in your repo data..
You may want to try the beta builds for trusty, as those are much more
up to date than the abandoned 0.15.x branch.
