Invalid Plugin does not contain top-level init.py file

[bporourke2]

I tried to install the plug in but get the following error.

calibre, version 4.14.0 ERROR: Unhandled exception: InvalidPlugin:The plugin in u'C:\Users\l[user]\Downloads\DeDRM_tools-master\DeDRM_tools-master\Obok_plugin.zip' is invalid. It does not contain a top-level init.py file

It does not contain a top-level init.py file

Before you try to tell me I am installing the whole directory, I am not. I unzipped the DeDRM_tools-master.zip and then within that folder there is the folder "DeDRM_tools-master folder, and within that folder there is a subfolder named "DeDRM_plugin". I tried to add that folder but it is not a zip so that didnt work. I zipped the folder and then tried to install from that to no avail. I still get the same probelm, even though there is a init.py file.

The file below shows the main file directory within DeDRM_plugin download. I zipped the 2 zip files myself.

Does anyone have an idea of what to do?

Opening post was trying to install the wrong file. Different issue here. Not compatible with Python 3 yet.

Having the same issue trying to load the DeDRM plugin on Calibre 4.15 for Mac (Mojave).

[ElleKayEm]

Hmmm, it looks like you're loading the correct file and that should work. Give it another try?

Download DeDRM_tools_6.7.0.zip from here:

https://github.com/apprenticeharper/DeDRM_tools/releases/tag/v6.7.0

Unzip DeDRM_tools_6.7.0.zip. Then load DeDRM_plugin.zip.

[AdmiralWright]

The link is where I got it from. Just tried loading it again. Same error.

[ElleKayEm]

Unzip DeDRM_tools_6.7.0.zip. Then when you load DeDRM_plugin.zip into calibre, make sure you are navigating to the folder DeDRM_tools_6.7.0 and not to the still zipped archive with the same name.

[AdmiralWright]

Still getting the same thing. Bummed out. :(

[ElleKayEm]

After you unzip DeDRM_tools_6.7.0.zip, rename the unzipped folder something like "unzipped DeDRM tools". Do not unzip DeDRM_plugin.zip. Then be sure you're loading DeDRM_plugin.zip from inside that renamed folder.

Hi! I've got a quite similar error message on Ubuntu 20.04 as one described above. Does it also have to do with the Python 3 compatibility issue or is it something else? And if it's this issue what are prospects to get the compatibility soon? Or I just need to switch back to a python2 version in order to install the plugin?

[ElleKayEm]

Yes, your issue is because you're using a version of calibre with Python 3. Python 3 compatibility is being worked on. You can look at the threads here discussing it. In the meantime, I believe calibre-ebook.com and flathub.org still have Python 2 versions of calibre.

[kend650]

Any idea of when the Python 3 version will be available? 1 Month, 1 year, ???

This is a community garden. If you want tomatoes, you're welcome to start digging.

Use calibre 4.23 and DeDRM 6.8.0. Make sure you are unzipping the main archive and loading just DeDRM_Plugin.zip into calibre.

[Yolakalemowa]

Looks like this issue has been resolved... latest DeDRM (7.2.1) is compatible with latest Calibre (5.39.1)

[ElleKayEm]

DeDRM has been compatible with calibre 5.x for a year or so now. Find the latest over here: https://github.com/noDRM/DeDRM_tools

I have this problem while using Calibre 7.5.1. I have tried to install DeDRM plugin 6.7.0, 7.2.1 and 10.0.3. All of the DeDRM fail to install with the message:

Please advise.

[ElleKayEm]

Use DeDRM 10.0.9. Unzip DeDRM_tools_10.0.9.zip and load DeDRM_plugin.zip into calibre.

https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9

[sheepdoggie]

Result with 10.0.9 when installing from the DeDRM_tools.zip: calibre, version 7.5.1 ERROR: Unhandled exception: InvalidPlugin:The plugin in '/home/mel/Downloads/DeDRM_tools_10.0.9.zip' is invalid. It does not contain a top-level init.py file

But unziping and installing from the DeDRM_plugin.zip does not have the error. It does install. Thank you.

[docborg98]

I am using calibre-64bit-7.7.0 and I have tried several version of the DeDRM zip. I always get "Invalidplugin C;\users.........DeDRM tools.....zip is invalid" It does not contain a top level _init_py file. I have spent hours on this and am so frustrated.

[ElleKayEm]

@docborg98 Download from the first link under Assets on this page: https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9

Unzip only that main file. Make sure your browser isn't automatically unzipping anything on download. Load DeDRM_plugin.zip into calibre.

[docborg98]

Thank you - I cut and pasted just the zip file for the plug in and that worked. When I clicked on the original zip file to get to the plugin, it wouldn't work!

[ElleKayEm]

Well, I guess that works too. I just unzip the main file and then retrieve the plugin zip file from the unzipped folder. Not from inside the original still zipped up file.

[GommT95]

When in Calibre, attempting to install the plug-in, I cant even locate a plug-in file (I've tried literally everything you have suggested but for whatever reason my PC cannot locate it)

[ElleKayEm]

It's going to be whereever you download it to. I put it on my desktop as that's easy to navigate to.
