Calibre 6.3 and DeDRM v10.0.3 -> removal Problem

[synthesechess]

Hi,
I'm trying to remove/ convert the DRM from a pdf. It's not working but I got this log:

Any ideas for a solution?

Thank you so much!

Since you're using DeDRM 10.0.3, you might want to ask over at noDRM's repo instead of here at Apprentice Harper's which ended with 7.2.1.

Sorry, but do not understand. Can you explain?
Tank you so much.

You're posting on Apprentice Harper's GitHub repository which is no longer maintained. Last release was DeDRM 7.2.1. The version you're using is 10.0.3 from noDRM: https://github.com/noDRM/DeDRM_tools

Understand. Thx!
