I actually opened a bug there and after (s)he looked at the logs, they found out that the plugin is not the issue but the Calibre viewer.

It's the first book from Kobo with which I am having issues with On /var/folders/nf/s70ywbcn4cjcphy4y6m2bgdm0000gn/C/calibre_5.37.0_tmp_0ux1v8ix/jogx圓aw.epubįailed to run pipe worker with command: from _book import viewer_main viewer_main()įile 'runpy.py', line 194, in _run_module_as_mainįile 'calibre/utils/ipc/worker.py', line 196, in mainįile 'calibre/srv/render_book.py', line 823, in viewer_mainįile 'calibre/srv/render_book.py', line 814, in render_for_viewerįile 'calibre/srv/render_book.py', line 792, in renderįile 'calibre/srv/render_book.py', line 605, in process_exploded_bookįile 'calibre/srv/render_book.py', line 264, in create_cover_pageįile 'calibre/srv/render_book.py', line 217, in find_epub_coverįile 'calibre/ebooks/oeb/polish/cover.py', line 284, in find_cover_image_in_pageįile 'src/lxml/xpath.pxi', line 430, in ._call_įile 'src/lxml/apihelpers.pxi', line 41, in lxml.etree._documentOrRaiseĭoes anyone has any idea what to do or any alternatives to try out?

It neither works with the DeDRM plugin by downloading the file via Digital Editions nor does it work with the Obok plugin and the Rakuten macOS app installed. However, the conversion in Calibre fails. I tried to convert a book I bought via Kobo to be able to read it outside the Kobo ecosystem. On macOS, you can do that with unzip filename.epub and then you should see all your images :)

I thought, it was a DeDRM bug but it is a Calibre viewer bug which cannot deal with a book that only contains images. If anyone gets a similar issue that the Calibre viewer shows an error for Manga after decrypting, you just need to unzip the decrypted ePub.
