HI @zynthianers!  
It seems that last images have problems. As i’m in a little country house, my band is really small and i can’t test the latest SD images. This is the reason i have not released a new SD image. I will visit Barcelona in the next days, so ii will download and test some of the latest SD images. Mean while, could some “advanced” user help me to confirm/identify the problem?

Thanks a lot!

I’ve been working from 2020-05-14-zynthianos-buster-lite-1.0.0.img

and that seems ok for me.

Please, could you test this image, or better, the last one from today. If you and somebody with a v3 zynthian could confirm it works OK, i could mark it as RC2 and avoid more headaches with recent SD images until i can do my own test …

Of course, the more testers, the better …

Let’s concentrate on yesterday’s image that seems to be good:

[https://os.zynthian.org/2020-05-22-zynthianos-buster-lite-1.0.0.zip](https://os.zynthian.org/2020-05-22-zynthianos-buster-lite-1.0.0.zip)

If this doesn’t work, we can try with 2020-05-14 or any other recent SD image that somebody had already tested.

Thanks a lot!

This is really a very useful idea, I’m switching to 2020-05-22.

And there we have a candidate! After an hour I give up. I can’t get it to run. 2020-05-14 was deleted?

</div>

Could you be more specific about the problems you found?

Ups! Regarding 2020-05-14, the auto-delete system probably get ride of it. It deletes SD-images older than a week if they are not marked as RC.

But if we don’t find another working SD image, @wyleu can upload his copy to the server 😉

Hi @spurkopf,

Please, could you send the webconf log?  
Simply type:

```
journalctl -u zynthian-webconf -f 

```

And try to access from the browser. Then copy/paste the output from the console. With this i could figure where the problem is and try to solve it for the next SD image builds.

Thanks!

No sorry, 2020\_05\_22 is already deleted. I have a copy of the 2020\_05\_17 UI log - I’m uploading it. But why mess with it, wouldn’t it be easier if you could say - this image worked for me - please test it?

- changed to custom kit and Mcp23017 Encoders - now they are working too
- switching of single mode, activating midi clock internal and setup wifi  
Now it should all working. 😓

Zynthian doesn’t detect hardware, apart from the RBPi. SD images are pre-configured for a given hardware combination, depending on the image date. The latest ones are pre-configured for “Kit V3 - Pro”. What is your kit version @spurkopf?

OK! I found the problem with mutagen and the SD build script:

```
# Install Mutagen (when available, use pip3 install)
$ZYNTHIAN_RECIPE_DIR/install_nutagen.sh

```

I just launched a new build for today (2020-05-24). It will finish in about 4 hours, about 21:00.

Ok, thank you.  
So far, I think running

```auto
$ZYNTHIAN_RECIPE_DIR/install_mutagen.sh

```

should solve the problem.  
So except that “mutagen” bug, this version should be like the next one.
