Common Issues with DeDRM Calibre Plugin and How to Fix Them
DeDRM Calibre is quite effective for removing DRM from eBooks; however, it can occasionally encounter some issues. Below are some common issues you may experience with the DeDRM Calibre plugin:
Problem 1: Calibre SyntaxError
Certain plugins, such as the DeDRM plugin, cannot be installed on Calibre version 5.0 or higher, which may lead to a SyntaxError. This issue can occur if you are still using an outdated version of the DeDRM plugin.
Solution: Kindly download and install the latest DeDRM plugin which works smoothly and efficiently with Calibre 5.x.
Problem 2: "Failed to decrypt with error: Cannot decode library or rented eBooks."
It is important to understand that DeDRM is not effective on rental or loaned content (e.g, titles from subscription services like Kindle Unlimited or Kobo Plus), because you don't have ownership of borrowed eBooks.
Solution: Make sure that your book is not a rented book, because the DeDRM plugin works only for books that you have purchased.
Problem 3: DRM cannot be removed from Kindle books obtained from Kindle for PC/Mac or a Kindle device.
The Calibre plugin is unable to recognize the books you have downloaded. You need to locate the Kindle books and drag them into the Calibre library. Moreover, the DeDRM plugin will not work if the Kindle for PC app has been updated to version 2.4.1 (70946). In this case, you may encounter an error stating "Failed to decrypt KFX DRM voucher with any key," and the imported Kindle books will be converted into KFX-ZIP format, remaining DRM protected.
