Can't decrypt ePub-eBooks on Ubuntu

[tomasmueller]

Calibre: 5.21.0

DeDRM: 7.1.0

I have downloaded the ePub-eBook using Adobe Digital 2.0.1 on Windows and imported the eBook in Calibre on Ubuntu 20.04. The Books (and all other Books) could not been decrypted. In the log there is a Path to Python, but its a Windows path. I don't unterstand why. On Linux Python3 in installed.

DeDRM isn't able to grab the key from ADE. You could try running adobekey.py manually and importing the key. Or it may be easier to temporarily install Windows calibre with DeDRM where you have ADE installed. If you successfully DeDRM a book there and save the key, then you can import the key into Linux calibre's DeDRM customization.

[tomasmueller]

I have no windows installed anymore but a windows 7 in a virtual machine. but calibre isn't running on windows 7. i will try to install an newer windows and test it.

is there no way to extract the adobekey manually? ADE is running on windows 7.

do you mean running the adobekey.py on linux? where can i find the file?

[ElleKayEm]

You could use calibre 3.48 and DeDRM 6.8.1. No, I mean running adobekey where you have ADE installed. It's one of the scripts in the DeDRM plugin. But the Windows calibre/dedrm workaround avoids needing Python and whatever else installed in the virtual machine to run adobekey.

[ivan-m]

When the DeDRM plugin detects that it's running in Linux it will assume that you have Adobe installed in Wine to get the extraction key.

You can try my Ansible script to install and configure Adobe DE in Wine for Calibre: https://github.com/ivan-m/ansible-dedrm-wine/
