Hi

After updating my server to Debian trixie, mopidy-local has an error. Mopidy is still working. Am I too early for an update?

This command: `sudo journalctl -u mopidy`

has related to the problem the same output like: `sudo mopidyctl config`

If I am to early, no problem. I did the test with a dd copy of my root file system. So there is nothing lost…

Short answer, yes. Mopidy-Local doesn’t support Python 13.3 due to [PEP 594 – Removing dead batteries from the standard library | peps.python.org](https://peps.python.org/pep-0594/#imghdr)

I think the workaround might be `sudo apt install python3-standard-imghdr`, can you try that? We need to fix Mopidy-Local. Weird nobody else (arch users?) flagged this sooner.

Thank you! I did install `sudo apt install python3-standard-imghdr` and after restarting the server the configuration didn’t show an error anymore. Then I did run `sudo mopidyctl local clear` and after this `sudo mopidyctl local scan` . And that’s what showed up in the terminal:

```

What is causing this?  
FYI: I did a fresh trixie install with a new image and the same thing happened there, same error on mopidy-local

A bug in newer release of GStreamer. See [add workaround for gstreamer 1.25.0 to 1.26.2 by girst · Pull Request #2200 · mopidy/mopidy · GitHub](https://github.com/mopidy/mopidy/pull/2200)

Thanks a lot @kingosticks! I deleted the existing `scan.py` at `/usr/lib/python3/dist-packages/mopidy/audio/scan.py` and copied the one from your mentioned workaround there. And it works 😃 Cool!!!

Hi David,

where did you get the correct scan.py?

Hi

I wasn’t able to find the file scan.py on mopidy anymore. But I did save the file back then and did copy the content below. So you just need to copy the content into your file.
