Cannot de-drm Nook books (epub/PDF) even WITH key #50

Open digitalfreaknyc opened 2 years ago

Question / bug report

Tried to de-drm books from B&N today and it mostly did not work.

Out of the 7, 2 were DRM-free, 1 was taken care of by De-DRM and the other 3 did not work. 6 were epubs and 1 is a PDF.

When I first got them (well, 6 of the 7) in 2021, I was able to de-DRM them with no problem. Now, clearly, something has changed.

The log I'm including here is for the PDF. I can include the epub one as well.

Which version of Calibre are you running?

5.38

Which version of the DeDRM plugin are you running?

10.0.2

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

No response

Thanks for the report. 7eb8f07a33c28a49452a9755742d535ac8a33ed2 should hopefully fix the issue with your PDF file. You can click on "Actions", then the latest workflow run, then on "plugin" under "Artifacts" to download a test version. Let me know if that fixes the issue with your PDF. As for the EPUBs, if this didn't get fixed with all the other changes that have been done to the plugin in the meantime, I'm going to need a debug log from one of those as well.

Nope.  Unless I downloaded the wrong version of the file....it didn't work.

Interesting ... I'm going to try and add some more verbose logs to the plugin to track this down. Thanks for testing.

I'm having the same issue, I think. Happy to provide any logs or info that may be helpful.

Just found https://github.com/noDRM/DeDRM_tools/discussions/9 and it worked perfectly for me - @digitalfreaknyc try it?

That's a different bug than the one reported by digitalfreaknyc. Your bug should now be fixed with dcbb3775667ab716f2da0c61d97000750cd7f88e. @digitalfreaknyc can you provide a log for an unsuccessful EPUB file? Maybe these contain more useful information.

@noDRM ack, sorry to clutter! thanks for the info.

They all work now, after that latest update. The only one that doesn't is the PDF...which is the only one I needed to convert in the first place :) :)

digitalfreaknyc commented 2 years ago

Would it help to send you the PDF file?

Interesting ... I'm going to try and add some more verbose logs to the plugin to track this down. Thanks for testing.— Reply to this email directly, view it on GitHub, or unsubscribe.

Maybe, if you're comfortable sharing the PDF and your Nook key string / key file (which you can export in the plugin settings). My email is in my Github profile.

I tested your PDF, but I can't get it to work at all, no matter what I do. Neither my fork, nor the latest original version, nor the 6.2.0 (latest Python2 version) seems to work. Maybe B&N PDF has always been broken? Or something is wrong with your PDF or your keys ...

According to the release notes, the script for B&N pdfs was first added with DeDRM 6.8.0, but it wasn't integrated into the plugin. And Apprentice Harper wasn't able to test it.

Like I said, the key now works on the epubs, no problem. And the PDF works in the app on Windows. I guess there's something else going on with PDF's...

No problem.  Would it help to send you the file?
