The question is quite old, but people like myself still trip up on DRM locked ebooks. I assume you want to get out of the acsm a DRM-free epub. My instruction is for Ubuntu/Debian using apt-get, but the tools exist for other distros as well. I need a couple of tools in particular: the DeDRM tool for python2.7 and wine. On wine, we will install Adobe Digital Editions, python and pip for windows

1. Install wine and winetricks because we will run Adobe Digital Editions in wine. By default ubuntu19.10 intalled wine 4 on my machine. Its easier to upgrade to wine5 first. ADE works so much better with wine5.

    sudo apt-get install winehq-stable winetricks winbind
   

2. Install dotnet40

    winetricks dotnet40 
   

3. Now download Adobe Digital Editions for Windows and install it:

    wine Downloads/ADE_4.5_Installer.exe 
   

4. After installing and launching DigitalEditions you will need to authorize you computer or log in with your adobe id if you don`t have one create it for free.

5. Open in ADE the acsm file. It will download the epub into your user documents folder (e.g., ~/Documents ) in sub dir "My\ Digital\ Editions". Note that the file is still DRM protected.

6. Now its time to run DeDRM from python wine. Unzip DeDRM tool Version 6.x and locate the adobekey.py file.

7. Download VCForPython27.msi, we need it for pycrypto

8. Install python, pip, vcforpython, and pycyrpt:

    winetricks python27 # this should also install pip
    wine msiexec /i ~/Downloads/VCForPython27.msi
    wine python.exe -m pip install pycrypto
   

9. Run adobekey.py from the dedrm you downloaded before with wine python:

    wine ~/.wine/drive_c/Python27/python.exe adobekey.py 
   

10. You get the adobekey_1.der that you need to run the other script:

     python ineptepub.py adobekey_1.der ~/Path/to/drm_locked.epub your_drm_free_out.epub
    

    For pdfs use 'ineptpdf.py' inststead of 'ineptepub.py'. If you get an error in this step about python, adjust the term 'python', to 'python2' or 'python3'.

11. You should get the output:

    Successfully decrypted drm_locked.epub as your_drm_free_out.epub
    

Done. Read your epub on any epub reader, e.g., okular, readera, lithium.

To be sure, this is quite a few steps. However, ADE is not a good reader, and the reading experience using wine even worse. I disagree that removing DRM is not legal; for personal use it's perfectly fine to remove DRM from your purchased ebooks. Publishers, of course, have an interest in reducing and controlling access to the material. EFF has some interesting articles on DMCA, DRM, and copyright. Have fun reading.

    wine ~/.wine/drive_c/Python27/python.exe adobekey.py
