Calibre Web Automated Kobo kepub download issue

[Runnerbeen]

Hi

I'm not sure anyone will be able to help as it's a bit of a niche question. I'm trying to use Calibre Web Automated without much success. Specifically when I try to convert a book to kepub I receive an error no 8 message - exec format error. I've downloaded the binary and put it in the usr/bin and set r w permissions so not sure what is going on.

Also does anyone know about book cover sizes? I've set a specific book cover size but when I download the book to my Kobo over the web it sets it to something else. I've run the cover enforcer command but this has made no difference.

Thank you

What platform is your Calibre Web Automated runnig on?

Is the binary you've downloaded for the same architecture??

It’s running on a Raspberry Pi 5. I have compiled the binary using Go and have
Run chmod on it. I also tried the Arm64 version but received the same error.

Thank you

Will the binary run from the command line?

Yes it does - I’ve been able to convert an epub to a kepub.

Does the go code need a runtime library that's not to present? I presume CWA is in a docker container?

I'm now out of ideas. Sorry

No don’t worry. Thank you very much for your time. I’ll check out if a runtime library is needed. CWA is in a docker container.

Thank you again.

[PeterT]

Have you double / triple checked the executable you've copied in within the container itself?

Something like
docker run -it <cwa_container> bash

and then ls -la <path to kepubify>
or
<path to kepubify>

[Runnerbeen]

The executable wasn't in the container - i"ve moved it now but can't see it in the file picker for the kepubify binary. I have definitely set read and write permissions.

This is a snapshot of the logs. It looks different now in that I can't see any kepubify errors.

Sorry I should also add that the book I'm trying to synch has been converted to a kepub already. I thought I should try that to try and narrow it down.

The errors above look like the ones someone else decsribed when they had notebook synch turned on. I've turned that off.

So it seems I can't covert to kepub using CWA or synch a book that's already a kepub.

Thanks for your suggestions so far.

[Wiggo]

If I were you, I would ask at CWA GitHub directly.

[Runnerbeen]

Thanks all, I'll put this on the back burner for now. I'd rather spend time reading than fiddling with this. I'll go back to Calibre which does what I need. Thanks again.
