DeDRM 10.0.9 not working (lcpl -> epub -> Calibre+DeDRM)

[xlor37]

Hi !
With Calibre 7.24

I tried to delete DRM from a lcpl file booked from my local library. I have it in paper but anyway.
I converted it in epub format with Thorium thanks to my password. No problem.
I used Calibre+DeDRM 10.0.3 (and then 10.0.9) with the epub file, nothing happened.
When I try to open it on Calibre it says "It's locked with DRM !"

Actually I tried to do it with Epubor Ultimate, it tells me that it was an Unkown DRM...

Is there any way to go forward with that issue ?

That DRM is no longer supported here because Readium issued a takedown of this GitHub repository until it was completely removed from the tools here. You might be able to find an old version of DeDRM somewhere out there which still has the lcpl scripts in it. However, even that may no longer work with the current version of their DRM. I don't know.
