Unable to remove KFX DRM with Calibre 6.29 + Kindle Paperwhite + DeDRM #429

Closed evsv closed 8 months ago

Question / bug report

Hi! I'm trying to use the DeDRM plugin to remove the DRMs on my Kindle KFX files. I've unfortunately been unable to do so. I used both the stable version (10.0.3) and the RC1 (10.0.9) on Calibre 6.29, and nothing seems to be working. Looking into the log file, the specific line of error reads "Failed to decrypt with error: The .kfx-zip archive contains an encrypted DRMION file without a DRM voucher:. The same error occurs both in version 10.0.3 and 10.0.9.

Other specs: I'm running calibre on Fedora 38, installed using the installation script provided on their website.

Thanks in advance, and thanks for all your hard work!

Which version of Calibre are you running?

6.29

Which version of the DeDRM plugin are you running?

10.0.9

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

Kindle FW: 5.16.2.1.1

As the log says:

Cannot locate some files needed for the book. KFX files must remain in their original folder structure for successful import.

@ElleKayEm , thank you so much! I was initially using calibre to transfer the files to disk, and that copied only the kfx over. It works perfectly now that I copy the kfx from it's original folder structure. Thanks again!!
