Probably being silly here. I have ubuntu setup with nzbdrone using the repositories. I have set the branch to develop branch but I am unsure on how to update it to such.?
The Ubuntu packages are currently based off of develop anyways, changing it in the UI will just show you the updates in the UI properly. Updates on Ubuntu are done the same way you installed it (via apt-get): https://github.com/NzbDrone/NzbDrone/wiki/Installation#ubuntudebian
It does say that the latest version is 2.0.0.990 but I am on 2.0.0.974??
Sorry, its actually running off the master branch now, to switch you will need to change a line in /etc/apt/sources.list
change: deb http://update.nzbdrone.com/repos/apt/debian master main
to: deb http://update.nzbdrone.com/repos/apt/debian develop main
And then:
sudo apt-get update sudo apt-get install nzbdrone
