Hello everybody.
I’m new to this forum.

I’m converting some ebooks from EPUB to MOBI format via command line.
I'd like to use Calibre via command line, but there is a problem about the cover.

In the EPUB, in the content.opf file, in the <spine>, the cover page has the attribute linear set to "no" (<itemref idref="cover" linear="no" />).

If I export the EPUB file directly with Calibre the thumbnail of the cover appear in Kindle application (see attachment).

While if I export the EPUB file via command line, the thumbnail of the cover doesn't appear in Kindle application (see attachment).

This is the code:
ebook-convert 9788852013089.epub 9788852013089.mobi --input-profile=sony --output-profile=kindle

What is wrong about my code?


Thanks in advance.
