NZBGet general....

Ok, I didn't even closly and who was doing rnextras.com.  I had to SSH install Sonarr and it works great, but it wasn't easy, but it does auto update on it's own.  You can do the same and download NZBGet at the source, the Linux version and SSH install that yourself and it should also allow updates as it should that way.  But again, it's risky.  If you NAS it backed up and if you screw things up, factory reset it again and maybe first get NZBGet working first and then restore all your data.  

It would be much simpler of course to just download a .deb version and install that and have everything work simpley.  For example PLEX does this. They have versions for a bunch of NAS's ad Windows, Mac and Linux.  They call get updated at teh same time.  It won't auto update, but you can just download the newest copy and install and all is good.   PlexPl will auto update, so does Headphones, and SickRage which I was using before I got Sonarr working.  SickRage I can easily turn on/off so it's off, but I turn it on once i a while and update it and turn it off again as a backup to Sonarr.  Sonarr I can't easily turn it on/off.  I can shut it down in the app but it'll reboot when the NAS reboots.  I'd have to go in with SSH and kill the starting script for it.  

If you be nice if whocares version of NZBGet update feature actually worked.  The currant version I'm using,16.4 works just fine and so I'm not in some huge rush to update at this time.   At some future point, maybe that will change.  I can either so back to SABnzbd which I don't like as much, or try my hand with SSH NZBGet also.  I'm in no way a Linux Person.  It's what little I know in all my years of using computers starting with a Vic-20 and a tape drive and a lot of Google seaches.  If I had a computer that I could run Linux on, I might try my hand at creating a deb package to install some of these App's onto a ReadyNAS easily.  Maybe that's something I'll get into at some point.
