There has been a fork with the NZBGet: https://github.com/nzbget-ng/nzbget Details:
Note: this repo is a fork of the original github project nzbget/nzbget originally written by @hugbug. He deserves all the credit for this software.
Since he has now archived the project, I've combined my changes (surgical fixes to accomodate the intentially-malformed 'wtf' NZB headers, which result in the infamous 'abc.xyz' file names) and merged several pull requests from the original repo.

I'm hoping that LinuxServer will point to the fork. I'm guessing no, but I can hope.
