So I updated my NZBGet without paying too much attention ... which got me the test release v17.0. Normally not a big deal, but ... this one kept crashing and there is no obvious way to downgrade from the NZBGet GUI. I wanted to go back from v17.0 (testing) to v16.4 (stable), and this is how I did that:
1. Stop NZBGet if you have it running and with SSH go to your QNAP.
2. On the command line, go to the NZBGet QPKG directory:
3. Grab the latest NZBGet build (one single line!):
wget -O - http://nzbget.net/info/nzbget-version-linux.json | sed -n "s/^.*stable-download.*: \"\(.*\)\".*/\1/p" | wget --no-check-certificate -i - -O nzbget-latest-bin-linux.run
This will download the latest STABLE version.
4. Run the installation:
chmod +x nzbget-latest-bin-linux.run
This will take a bit, but once it's done ... you have the latest stable version running once you start NZBGet from the App-Center again
