What is NZBGet?

NZBGet is an Usenet downloader, it will download releases from Newsgroups and where required will also repair and extract releases. It works on its own or in conjunction with other tools such as Sonarr and Radarr.

Lets Begin

In the guide I will be taking you through the steps to download and setup NZBGet in Docker.

In order for you to successfully use this guide please complete the two preceding guides

Downloading the NZBGet Image

Open up Docker within DSM and navigate to the ‘Registry’ tab, then search for ‘nzbget’. In the list of available containers select the one made by Linuxserver as shown below and click on ‘Download’.

The pop-up box will ask which version you want to download, make sure you choose ‘Latest’ from the list of available versions.

You can check the status of the download over on the ‘Image’ tab.

Setting up the container

In Docker click on the ‘Image’ tab, in the list of your containers select the ‘Linuxserver/ NZBget’ image and click on ‘Launch’

You will now see the initial setup screen, you can change the name of the container, we are not going to change the resource limitations.

Next up we are going to click on the ‘Advanced Settings’ button, this will take you to a new window with a number of tabs which we are going to work through.

On the first tab enable ‘Auto Restart’ this will ensure NZBGet will automatically start up whenever you reboot your NAS.

Volumes / Mounts

We can now move onto the volume tab in which we will be specifying the directories where NZBGet will store its configuration files and where to store in progress and completed downloads.

Click on Add Folder, click on the docker folder and create a new sub-folder called ‘nzbget’ select this folder and click ‘select’

This first folder will map to /config in the mount path section.

Click Add Folder again and this time select the ‘data/usenet’ folder and click Select.

In the Mount path section for this folder enter ‘/data/usenet’

Your mounts should now look like the table/screenshot below.

File/FolderMount path
docker/nzbget/config
data/usenet/data/usenet

Network

We are not going to be specifying specific ports for NZBGet to use as we want to keep things simple, tick the ‘Use the same network as Docker Host’

This image has an empty alt attribute; its file name is radarr04.png

You do not need to set up anything on this tab.

Environment Variables (PGID,  PUID and Timezone)

Next we are going to set up a couple of environment variables that docker will use to allow the container access to our files and folders and also to tell it where we live in the world.

Click the Add button, and fill in the following details as per the table/screenshot, you will need to do one at a time.

variableValue
PUIDThe UID you obtained in the user setup guide
PGIDThe GID you obtained in the user setup guide
TZYour timezone wikipedia.org/wiki/List_of_tz_database_time_zones

Now click on apply, and you will be taken back to the initial screen, click next, and you will see a summary screen. Check your settings are correct and click on Done, the container will now start up.

Some final steps

NZBGet will now be running, you can connect to it by going to the IP address of your NAS and port 6789

e.g 192.168.0.40:6789

The default login details are:
Username = nzbget
Password = tegbzn6789

To make sure you file ‘path’ settings are correct, go into settings and change the following value.

PathPath to enter
MainDir/data/usenet
only change the MainDir setting all the paths below it you do not need to touch

You have now completed the setup and can begin using NZBGet.

Docker Compose

You can use the below code saved as nzbget.yml in the ‘/docker/nzbget’ share, this will do the entire process above in one quick command via SSH. Ensure you change the variables to your own.

version: "3.8"
services:
  linuxserver-nzbget:
    image: linuxserver/nzbget:latest
    container_name: nzbget
    environment:
      - PUID=YOURUID
      - PGID=YOURGID
      - TZ=Your/Timezone
    volumes:
      - /volume1/docker/nzbget:/config
      - /volume1/data/usenet:/data/usenet
    network_mode: host
    restart: unless-stopped
sudo docker-compose -f /volume1/docker/nzbget/nzbget.yml up -d

    Thanks for these guides. I have followed them and everything is running, however, there seems to be a problem between spotweb and NZBGet. I am not see any activity in the NZBGet webui or the download folders. I can’t seem to find where I missed something. Can you point me in the right direction? Thanks!

    Hi Dr_Frankenstein,

    Thanks for the nice guides you have made.
    I’m using Sonarr for the TV shows and NZBGet to download. But after finishing your instructions I have a problem.
    My downloaded TV shows aren’t moved to the correct location (which is /data/series/{tv show name}). The file stays in /usenet/intermediate.
    Also I get an error in NZBGet:

    ERROR Thu Apr 14 2022 16:14:29 Could not delete temporary directory /data/media/series/Greys.Anatomy.S18E05.1080p.WEB.H264-PECULATE/_unpack: No such file or directory

    AND

    ERROR Thu Apr 14 2022 16:14:29 Unrar error code: 9

    Could you pls help?

    Kind regards,

    Paul

      Hey Paul, are you asking NZBGET to do the file moves or Sonarr?

      • Paul Paul

        Hi,

        I actually don’t really care, but i got the first part fixed. I created a directory manually Movies and Series (TV shows). Now Sonarr and Radarr seems to do their job. Not the nicest solution, but it works. But I also use Spotnet from my PC. I only get NZB files there and put them in the NZB folder of NZBGet. I add them to a category by hand like software or xxx. Since I’don’t use Sonarr or Radarr there I want NZBGet to put those files in the correct final location which is: /data/media/Software for software and /data/media/xxx for xxx movies.
        So if you have a solution for that, I’d like to hear it. 🙂

        Thanks in advance an kind regards,

        Paul

          If you create sub directories within the /nzb directory NZBGET will auto assign categories based on the directory name for example if you put your nzb in /nzb/tv it will have the TV category applied and once downloaded go into whatever option you setup for the category to move to once downloaded.

          • Paul Paul

            That works great indeed. Thx for the advice. But my TV shows seems to be handled by Sonarr and Radarr. The /usenet/completed folder has an directory movies and tv shows and both Sonarr as well as Radarr seem to pickup the files there and rename them and put them in /data/media/movies and /data/media/series. But Sofware for example is not handled by an app like Sonarr or Radarr. How can I get those files in the correct media folder (/data/media/software/)? Is that by adding /data/media/software/ to the “DestDir” of the respectively category?

          • Dr_Frankenstein Dr_Frankenstein

            Yes that should work for Software

          • Paul Paul

            Mmm it doesn’t work. I get an “Unpack: Failure”. any idea?

          • Dr_Frankenstein Dr_Frankenstein

            Sorry I misread your paths we only mounted /data/usenet to the NZBGet container, so it can’t actually see /data/media/software. If you tweak your mount point for the container to /data and /data it will work.

          • Paul Paul

            Thx a lot. it works like a charm now!!

    Hello,
    I always get the error message “(/data/usenet/nzb): could not create directory /data/usenet: Permission denied”. Do you know how to fix this?

    • Dr_Frankenstein Dr_Frankenstein

      Hey, double check your PGID and PUID to make sure you entered them the correct way around as a starter

      • Kevin Kevin

        Thank you for the answer.
        I checked the data and they are correct. I tried to switch accounts but still the same error. the full message is:
        ” nzbget.conf(46): Invalid value for option “NzbDir” (/volume1/docker/NZBGet/data/Usenet/nzb): could not create directory: No such file or directory”.
        I checked the folder permissions and everything is fine. I don’t understand where the problem comes from. And it’s the same with sonarr

      • Kevin Kevin

        I’m sorry, I just understood… The order was wrong… Thank you very much for the help

    Changed the maindir to usenet as it was written above. Lost all my previous download que. Can’t even cind where it was. Simply does not appear in any folder in synology. Previously maindir was set to /downloads which was not even mapped to it. Now it is mapped to /data/usenet and works fine, but lost every nzb file in the que. And could not recover them.

    Is there a fix to this?

    • Dr_Frankenstein Dr_Frankenstein

      Hey, unfortunately if you started downloads before changing the main directory the files are currently inside the container.

      You could try temporarily adding an additional mount point pointing to /downloads to see if the files then appear on your main file system and move them over to the correct mounted folders.

      Then remove the additional mount point and you can resume the downloads again. You may have to cut your losses and just redownload the files.

  5. Chris Chris

    Thanks for the manual. I do have a question. What comes in the data/usenet folder?

    • Dr_Frankenstein Dr_Frankenstein

      It will contain all the completed and temporary download files before that get moved to their final locations by Radarr etc.
