Wat een ellende is dit toch...
Is dit een goede manier?
This is the simplest way that I have found:
Install Adobe Digital Editions using winetricks
winetricks adobe_diged
Download and install ePUBee within the same wine prefix used by Adobe Digital Editions
$ cd ~/Downloads
$ wget
http://download.epubee.com/ePUBeeePUBDRMRemoval.exe $ WINEPREFIX=~/.local/share/wineprefixes/adobe_diged/ wine ePUBeeePUBDRMRemoval.exe
Start Adobe Digital Editions and login to your adobe account
Add your DRM'ed books and wait until they are readable (decrypted)
Run ePUBee. It should automatically decrypt any files added to Adobe Digital Editions to
~/.local/share/wineprefixes/adobe_diged/drive_c/users/${USER}/Application\ Data/decrypt/
Use Calibre or your favorite ePUB management tool to get the ePUB's onto your reader
