Just purchased a Kindle book azw format and could not to convert to epub. The error message was “cannot convert the ex files because book locked by DRM”. This is new - previously had no problem.
Figured that a new DRM Removal version was requited Looked for available plugins (get plugin to enhance calibre) and that plugin is not listed, then, looked under “change calibre behavior” to see if a new DRM removal tool was available under Advanced Plugins not located.
Closed Calibre and downloaded the newest DRM Removal Tools for eBooks version from Apprentice Alf’s Blog.
After download, opened 'Change Calibre behaviour' option under “Advanced” clicked on “Plugins” and clicked on 'Load plugin from file' in the unzipped Alf's tools , clicked on the DeDRM_calibre_plugin folder (DeDRM_plugin.zip file).
Tried to plug in v6.8.0(Jun 18)/ v6.7.0 (Feb 17)/ v6.6.3 (Mar 30, 2019) all unsuccessfully.

v6.8.0 - error message reads – SyntaxError:invalaid syntax(calibre-plugins.dedrm._init_line168)

My question is this.
Since the Apprentice Alf’s blog program is no longer compatible with Calibre is there another DRM removal Tools for eBooks for the Calibre Platform available for dowlnoad?
Calibre 5 Remove Drm
Calibre 5 Drm
Install Dedrm Plugin Calibre
In Calibre, click on Preferences, scroll down and click on Plugins in the Advanced section, Click on the “Load plugin from file” button on the bottom right of the Plugins screen. Find and select your DeDRM zip file. It should install and enable the plugin, which you’ll find in the File Type plugins section. One should first unzip the main folder, rename it, then inside calibre install the zipped DeDRM folder inside the unzipped folder. It's very strange, but it worked for me. I'll leave the post up for those who might run into future problem. (also to hear your suggestions about solving it for Calibre 5). Install Calibre and DeDRM plugin. Download the latest version of Calibre. Run the installer and select the type of eBook Reader you use. Choose the appropriate options to complete the installation.
