Downloading with SABnzbd failing

[gitnew12]

Using the dev image and setup up Prowlarr and SABnzbd. The nzb file is successfully downloaded and sent to SABnzbd where the download completes successfully but I get a Download failed.

I am assuming I am probably mounting the volumes incorrectly, I have this in my docker compose:

      - /mnt/user/media/Books/Ingest/Booklore:/books            # Book destination directory
      - /mnt/user/appdata/cwa-book-downloader:/config           # App configuration
      - /media/Downloads/Usenet:/media/Downloads/Usenet         # Download client mount - path must match your torrent/usenet client's volume exactly

I checked the logs and don't see anything about the download failing. The last log print is:

2026-01-09 00:15:13,401 - cwa_book_downloader.release_sources.prowlarr.handler - INFO - handler.py:151 - Added to sabnzbd: SABnzbd_nzo_5uagyo59 for '<file name>'

And this is my settings for Download Clients under Prowlarr:

Hi, can you retry with debug enabled and upload the ZIP file created here?

Just guessing at this stage but definitely make sure your - /media/Downloads/Usenet:/media/Downloads/Usenet is the exact mapping used in the SABnzbd container too, otherwise CWABD won't be able to find the file where SABnzbd saves it. Could be wrong though, the debug ZIP will help massively :)

[gitnew12]

I'm an idiot, it was user error. The solution was per your instructions:

exact mapping used in the SABnzbd container

In the docker compose files I had these volumes:

• CWA Book Downloader: /media/Downloads/Usenet:/media/Downloads/Usenet
• SABnzbd: - /mnt/user/media/:/media

Changing CWA Book Downloader volume to - /mnt/user/media/:/media resolved the issue and it worked!

Again, wonderful piece of kit. You have made leaps of progress! Thank you for this wonderful project.

One thing to note, though the file was moved, the download remained in SABnzbd under History. Anyway to include a cleanup process after successful copy to the Booklore ingest folder?

[alexhb1]

No problem! I'll have a look at the SABnzbd code and see if that's possible for a future release

[gitnew12]

I would imagine it would be similar to what Sonarr/Radarr does upon successful move.

Hey - sorry to jump on but having the same issue and cannot seem to get my head around it. My current voumes are:

volumes:
- /volume1/data/media/uploadbooks:/books # Book destination directory
- /volume2/docker/shelfmark/config:/config # App configuration
# Download client mount - path must match your torrent/usenet client's volume exactly
- /volume1/data/usenet:/data/usenet

The latter matching my Sab docker compose volume mount exactly. Within the Sab container itself, the directory for downloads is /data/usenet/completed.

I still get downloads failing. Should I be changing anything in Shelfmark settings in line with this? Do I need to point at the completed download folder in the Shelfmark compose? Do I need to do something with the category in Sab itself?

Any help is appreciated.

Could be a ownership/permission issue, are you running Selfmark as:

PUID=1033
PGID=100

You might also have to go and change owners/permission on the Selfmark data as well, I had to do this to get it working.

[redholt]

Thanks - will have a play around at weekend but think most of the permissions are already set. Can I check that you are not changing any values in the software itself i.e. the download location (cwa-book-ingest)?

Not sure if its relevant either but I cannot set the UMASK on shelfmark, seems to want to default to 18.

[alexhb1]

Hi, could you change your download destination in the app to /books? It should match your compose mapping.

[redholt]

Good spot, didnt even connect the dots there - Have updated but still get failures. It must be a permissions thing on my side so will have a play about at weekend.

[redholt]

Scratch that, updated the directory and restarted the container its working now! Thanks @alexhb1

It is not clear to me what the mounting should be for sabnzbd in the Shelfmark container. If my sabnzbd downloads are at /mnt/media-ssd/downloads on my host machine, where should this mount to in shelfmark?

[redholt]

Just copy whatever directory is in your Sab compose into the Shelfmark. So mine was - /volume1/data/usenet:/data/usenet which I just copied into the Shelfmark compose. Then make sure your mapping matches i.e. my download was still cwa-book-ingest but needed to be changed to books as per the compose.

Having issues myself here for this.. I'm using the default trash-guides setup that I usually do for other *arr apps within Unraid.

here's screenshots of what I have currently.

I'm using two downloaders, so I assume I can just directly point to the /data folder then correlate it correctly in Shelfmark UI

My prowlarr setup is working just fine, as it grabs the files and they are sitting in the /data/usenet/completed/books folder, but any attempts to move them to the /media/books folder fail.

[Cook13s7777]

/data:/data/mnt/user/data/ is my SABnzbd setup, following trash-guides mapping for hardlinks and such (I'm still using *arr apps as well, so I can't really change the folder mapping)

I'm adding my situation in case it helps anyone else. I was having trouble wrapping my head around how to connect a QNAP QPKG SAB install with Shelfmark. I felt like the error was telling me to use volume mapping in the container or remote mapping in settings, but it required both to work for me. Rather than detailing every failed step, here's what finally worked for me:

In my shelfmark volumes section:

      -       - /share/CACHEDEV1_DATA/.qpkg/SABnzbd83/SAB_CONFIG/Downloads/complete/books:/SABDown:/SABDown

This successfully created an /SABDown folder in the container that contained the downloaded books. However, Shelfmark was still receiving the message from SAB to look in the /share/CACHEDEV1_DATA/.qpkg/SABnzbd83/SAB_CONFIG/Downloads/complete/books:/SABDown folder for the downloads.

I fixed this with the following entry in Settings > Advanced > Remote Path Mappings:

  /share/CACHEDEV1_DATA/.qpkg/SABnzbd83/SAB_CONFIG/Downloads/complete/books:/SABDown to /SABDown

Reading other users' comments, I think I could change the mappings to stop at the "Downloads" or "complete" folders and it would find the books and audiobooks folders, but since I'm using Shelfmark only for ebooks at this point, the books folder works fine for me. I might change it later if I choose to try audiobooks as well.

I hate to ressurrect this but I've been having tons of trouble getting this to work with sabnzb.. All my mount paths match between Sab, Shelfmark remote mappings, and the docker compose, yet I'm getting "Fodler doesnt exist" errors on the completed download, and the folder definitely exists.

my volume mapping in the compose
/mnt/media/Downloads/completed:/mnt/Media/Downloads/completed

the remote mapping in shelfmark is identical to the above

in sab -

The error I recieve -

and finally the actual folder

I'm at my wits end with this and would appreciate any and all help.
