Question / bug report

I'm trying to access a course book for university and it's protected by Adobe DRM. I'm using Fedora 38, the RPM version of Calibre found from the official repos and Leseratte10's DeACSM plugin, but when trying to import and DeDRM the book, there is an error message in the log, and the DRM doesn't get removed. There is an error: AttributeError: module 'Crypto.PublicKey.RSA' has no attribute 'import_key'

5.43

Which version of the DeDRM plugin are you running?
