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

[noDRM]

Thanks for the report. 7eb8f07 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.

[digitalfreaknyc]

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 #9 and it worked perfectly for me - @digitalfreaknyc try it?

[noDRM]

That's a different bug than the one reported by digitalfreaknyc. Your bug should now be fixed with dcbb377.
@digitalfreaknyc can you provide a log for an unsuccessful EPUB file? Maybe these contain more useful information.

[junefish]

@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]

Would it help to send you the PDF file?

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.

[noDRM]

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 ...

[ElleKayEm]

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.

[digitalfreaknyc]

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?
