I suspect there's something broken in adobekey.py, a file which comes in the DeDRM_Tool. and run the Python Script which should extract the adobe key file, it gives me an error. That's fine, I managed to get the encrypted PDF by asking a friend who uses windows to download it for me on ADE. First of all, ADE runs on wine 5, but glitches and eventually crashes right when I try giving the Adobe ID credentials. I followed all the steps, it's nothing complicated at all. I've just run into this question How to read an ACSM file on Linux?, which seems to have a pretty satisfying answer. I've even run Epubor and used it on Wine, the program runs smoothly, but it didn't remove the DRM, unfortunately. I've tried for days using DeDRM_Tools as a Calibre plugin, it doesn't work.
