Obok Plugin Not Working on Some Books

[mslmn]

Question / bug report

The plugin doesn't work for some books bought on rakuten jp. Other books work but some output a filename with random numbers and letters and no cover in Calibre. When I try open the book I get this error

calibre, version 6.14.0 ERROR: Loading book failed: Failed to open the book at /Users/temp/Calibre Library/Unknown/sp167tdv (3048)/sp167tdv - Unknown.epub. Click "Show details" for more info.

Do they have Adobe DRM? How are you downloading them?

[mslmn]

Yes. I am downloading them through Kobo Desktop from the JP Kobo ebook store. Other ebooks downloaded from the same store work just fine.

[ElleKayEm]

If you're downloading them through Kobo Desktop, then use the Obok plugin to import them and remove DRM. Those have Kobo's own DRM, not the Adobe DRM that the regular DeDRM plugin handles. The ones that "worked" must have been DRM-free.

[mslmn]

I have been using the Obok plugin to import and remove DRM on all my Kobo files, including the ones that aren't working.

[ElleKayEm]

Sorry I was confused by the fact that this log just shows the DeDRM plugin. Let's see a debug log of adding it with Obok. Although I think the problem is in the books themselves:

KeyError: "There is no item named 'OPS/advanced.opf' in the archive"

It might be an issue with the books themselves. I've noticed the issue seems to be present on JP Jump comics specifically. #204
