Offiical Apt Repository Changed
Having recently posted to tell you all that I'd got http://apt.tvheadend.org back on-line supporting a more comprehensive suite of builds. I've now decided to follow dreamcat4 and move the official hosting to bintray (I needed a bit of time to investigate it and understand that it's a much better solution).
So the existing auto-build system that feeds http://apt.tvheadend.org has now been altered to post stuff to a new "official" bintray location.
It's my strong recommendation that people downloading packages for Ubuntu / Debian use the new repository as apt.tvheadend.org may eventually stop serving content (though no intention to do that any time soon).
