2 our of 39 books failed to remove DRM #602

Open EvanMaxGitHub opened 1 month ago

Question / bug report

I downloaded a batch of 39 books from Kobo that all had DRM on them (same series/author/format/etc.) I successfully loaded these books into Adobe Digital Editions on my Mac, and then from ADE to Calibre. I attempted to load the books to my 11th gen Kindle first without installing the DeDRM plugin, and was met with 40 "this book has DRM" pop-ups, which I now understand is to be expected.

I installed the plugin and attempted again, and the majority of the books now converted properly, but two books still gave em the error messages. I attempted to remove and re-add these two books multiple times, and to convert directly prior to adding them to my device, but met the errors on these books every time. Eventually I removed them and re-added them in debug mode, and I have attched the log from that attempt to this ticket.

Which version of Calibre are you running?

7.16.0

Which version of the DeDRM plugin are you running?

v10.0.3

If applicable, which version of the Kindle software are you running?

No response

That's weird. It is usually all or nothing. These were downloaded via ADE on the same computer and user as calibre/DeDRM? Same as the other books? I've seen DeDRM get overwhelmed if you try to add too many books at once to calibre. But it should have been fine when you added just these two.

EvanMaxGitHub commented 1 month ago

Yes, same computer, same user (for ADE, for Kobo, for calibre/DeDRM), same session, same everything.

I downloaded the books from the Rakutan Kobo webpage, and them opened the downloaded files in ADE. Then I loaded the epubs from the ADE documents file into calibre. 9I've also downloaded the Kobo Mac Desktop application and downloaded all of the books there, if there's any sort of workaround to use those files instead, but I haven't been able to figure anythign out.)

I thought it might be an overload thing at first too, but even when I try to load those two books in individually they still throw up the error.

As a test I installed Epubor Ultimate, and that seems to be able to get through the DRM on the books, but I'd rather not pay for a licence for that (required to export more than just 20% of them) just to get in to two books I've already paid for in the first place, when it seems like DeDRM should be able to do it.

ElleKayEm commented 1 month ago

Yeah, if Epubor can work, then DeDRM should work. Try DeDRM 10.0.9: https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9

Delete the Adobe key that is saved in DeDRM. Restart calibre and add your books.

You can import the Kobo Desktop books with Obok.
