Hello, José. > oscrypto.errors.LibraryNotFoundError: Error detecting the version of libcrypto
This bug was already fixed on DeACSM upstream development code. Try it from DeACSM plugin forum. https://www.mobileread.com/forums/showpost.php?p=4157570&postcount=2 https://www.mobileread.com/forums/showthread.php?t=341975 FYI: DeACSM plugin was renamed to ACSMInput plugin. Use "calibre-customize --add-plugin FILE_PATH" to install plugins from local path. https://manual.calibre-ebook.com/generated/en/calibre-customize.html -- YOKOTA
