Calibre DRM Removal for Ebooks on Linux - LinuxConfig.org


#1

Calibre is one of the best ebook tools out there. It's much more than a reader and a library. Calibre even helps you author your own ebooks. In addition to all that, it lets you remove DRM and convert your ebooks between formats. Think of it like a cross between Kodi and Handbrake, but for ebooks.

For me, installing and using Calibre on Linux wasn’t that simple. To actually be able to remove DRM, the plugin needs the user’s keys for the respective DRM platform. To be able to remove Adobe DRM from epub books, either Adobe Digital Editions, a Windows application, must be installed through Wine and DeDRM must point to the correct wineprefix path (which sometimes might be found automatically by the plugin, sometimes not, depending on how you use Wine), or those keys must be imported manually from somewhere. The procedure is similar for Kindle e-books, but even slightly more tricky, since it involves using an older Kindle for Windows application which has to be configured to not automatically update.

I’m having alot of difficulty with this. After many hours I was finally able to install ADE using winetricks (was impossible with just Wine) . Then in the final step in calibre, trying to customize the plugin, and it asks for the Wineprefix, nothing is working. I found some discussion online and it suggests “~/.local/share/wineprefixes/adobe_diged”, so I tried that but it doesn’t work, nor another suggestion on that page: “In WINEPREFIX put in /home/YOURUSERNAME/.adewine” . Whatever I enter for the wineprefix it just says “The Default encryption key for Adobe Digital editions could not be found”. So I’m giving up for now after struggling with this all night…
