Error message when attempting to convert Kindle book to Epub

[booooooookz-sys]

Hi,

First of all, thank you for the work you're puttin on the plugins!!!

I've installed it, found the azw9.md file in the Kindle library and successfully uploaded it into Calibre. When trying to convert it, I get this error message:

calibre, version 8.9.0 (darwin, embedded-python: True)
Conversion error: Failed: Convert book 1 of 1 (CR!R2JSGNYFSD1WN7M7TGZ7EA1N5EAG.azw9)

Halp!

Thank you,

An azw9.md is not the book. Looks like you are trying to decrypt something from Kindle for Mac and have an old version of DeDRM. None of those things are going to work. Unless you can use another method, you may be out of luck. See this post for info on the current state of dealing with Kindle books: https://www.mobileread.com/forums/showthread.php?t=361503
