Photon failing to download

[Jacob-Lasky]

Hi, love the tool! I'm having an issue with Photon. I want to download the global index (I travel a lot for work) but I'm having some issues. Here are what I believe are the relevant logs:

I have sufficient space to download

2026-01-08 14:40:01,066 - root - INFO - Sufficient disk space available for update

2026-01-08 14:40:01,761 - root - INFO - Starting download of 118.54GB to photon-db-latest.tar.bz2

But after a little while, it throws an error:

2026-01-08 15:49:26,526 - root - INFO - Download progress: 33.0% (39.18GB / 118.54GB) - 45.1 Mbps - ETA: 4h 12m

On the retry, it eventually throws another error:

and finally, it errors a third time:

I'm on UnRAID 7.2.2 using your image dedicatedcode/reitti:latest with the recommended photon image rtuszik/photon-docker:1.2.1.

The only change I made to the docker-compose is the volume path:

    volumes:
     - /mnt/user/appdata/reitti/reitti-data:/data/

Everything else is working perfectly!

Hi @Jacob-Lasky,

I never experienced it but i also never tried downloading the whole index. I had a look at the photon repo and there is a fix regarding resuming downloads. Please try going to v 1.3.0 for photon.

rtuszik/photon-docker#176

Hoping this helps.

[Jacob-Lasky]

I'll try it and get back to you, thank you!!

[Jacob-Lasky]

That fixed it! Thanks a lot

[dgraf-gh]

That is good. I will update the docker-compose files then. Thank you for taking your time to test it.
