This release isn't compatible with DeDRM for now according to:

> This release DOES NOT work with the latest calibre beta that requires Python 3 for plugins. (Updated June 2020).

So I'll have to wait until it is. DeDRM is pretty vital as I often buy books on Amazon and read them elsewhere.

And even if not, I would not "buy" books that are in effect protected and can be taken back from me at any time, without being able to do anything about it.

It's possible to use DeDRM tools from the command line, the plugin just makes it easier.

Simply git clone https://github.com/apprenticeharper/DeDRM_tools/ and then:

  python2.7 DeDRM_tools/DeDRM_plugin/k4mobidedrm.py \
    -k ~/.local/share/wineprefixes/kindle/drive_c/users/*/Local Settings/Application Data/DeDRMPrefs/kindlekey.k4i' \
    ~/Documents/My\ Kindle\ Content/book.azw .
or

  python2.7 DeDRM_tools/DeDRM_plugin/ineptepub.py \
    adeptkey.der book.epub book_dedrm.epub
(I'm not exactly sure where to get adeptkey.der but I'm certain it can be extracted from an old python2 Calibre + DeDRM installation.)
