Adobe DRM on linux recently got a lot better: https://superuser.com/a/1775619 https://superuser.com/a/1775619 Copied for posterity: --- It's now possible to do this 100% within Linux, without running any emulators or Windows software, even though Adobe don't care about Linux support. Knock is no longer maintained, however apparently it was just a wrapper around libgourou which is still maintained. Installing libgourou (on Arch Linux it can be found in the AUR) allows you to download the ACSM file to a PDF or ePub: # Use your username and password from https://account.adobe.com https://account.adobe.com # This registers your device so only needs to be done once. adept_activate -u user -p pass # Download the ACSM file acsmdownloader -f myfile.acsm The downloaded file requires a password to open it, but if you need to open it in a normal viewing application, you can also remove the password: adept_remove file.pdf This process allows Linux users to access the same materials as their Windows and Mac friends, even without support from Adobe. ---
