This worked or me on a Mac. Many thanks!

Yeah, I wonder if lcpdisliker used that repo to write his patch.

Well, I'll have a bash at installing it later on.

Your passphrase is your Netgalley's username.

Confirmed Russian code works on Netgalley's books.

Hi! New to this forum.

Just thought I'd mention I took inspiration from the approach detailed in OP's blog (big thanks edent!), and created a script to automate the extraction of non-DRM EPUBs from Thorium Reader, and bundled it up in a Docker image for portable ease of use.

Thought it might be of use to others here?

I posted it with instructions over on the r/calibre subreddit.

Would be curious to hear from you guys to see what success you have if you try various ebook vendors/LCP versions etc?

Attaching Dockerfile here (rename to remove .txt-extension before building/running) in case it gets removed from the subreddit.

[Attachment removed. MobileRead will not host any DRM circumvention software.]

And the post has already been removed from Reddit. Apparently they don't want to annoy Readium.

I could conceivably also have run afoul of reddits anti-spam detection. I created a fresh reddit account for the purpose, and found a few old threads of people asking for help with LCP DRM where I crosslinked to my post asking if they might try because I was curious how generally applicable the script was, but perhaps that got flagged as spammy behavior.

I'll perhaps reupload somewhere later, but that will be some other day.

You will have to find a place to host your script and post the link to your script.

Link to convenience util based on OP's manual method.

Docker-based for portability.
Although anyone Linux literate can probably decipher it to figure out how to run it locally/without Docker too.

It uses Thorium Reader, like edent's manual extraction method (although headlessly), which I guess has its pros and cons.

e.g.
con: bloat/difficulty to embed/integrate in existing tools
pro: so long as Edrlabs release Thorium as a partially open source, Electron-based app can probably fairly easily be patched for whatever future updates they make (within reason of course).

Can you please make a Windows version as most people run Windows and that code will not work. Thanks.

It does work on Windows, just via Docker (so a lightweight containerized Linux).
I use Windows on my primary home computer and this tool was developed on it.
You could also use WSL (e.g. Ubuntu for Windows), I've verified that works too. But that's arguably more complicated to explain/guide someone through than Docker.

The nature of this type of tool (remote-controlling the Thorium App), is just so much easier to do in Linux (i.e. extraction of the official Thorium app, running it headlessly etc), that I doubt it is worthwhile to try to do as a native tool for Windows (at least nothing I have the time to take a stab at at the moment).

I'm looking for this to run under Windows with no Linux components.

This works great.
Here is the repo with the updated DeDRM plugin code:
https://gitflic.ru/project/xna83444/dedrm

Instructions are in the README.
You can also find the release zip file in the Releases section of the repository which can be used directly in Calibre.

Rather than continuing to call this version 10.0.9 how about a new version number?

Sure thing.
New release is active.
