Calibre content server and DeDRM

PatrickMarq · 09-19-2022, 03:37 AM

I can convert without any problems Kindle azw3 files on the command line with Calibre 6.X desktop.

Calibre 6.X desktop runs on another computer then my calibre content server.

I would like to convert these files on the content server without installing the Calibre desktop software.

I have tried to install the DeDRM tools on the content server with following command: calibre-customize --add DeDRM_plugin.zip
There was no error but the .config/calibre/plugins/ was empty. I have copied the files over from my desktop to the content server but still errors when converting.

1% Converting input to HTML...
InputFormatPlugin: MOBI Input running
on /mnt/multimedia/text.azw3
Found KF8 MOBI of type 'standalone'

So is this possible to convert without installing the desktop version ?

Judging from the log and the fact that the plugins folder is empty, it appears you didn't install the plugin at all. The log indicates that Calibre did not attempt to remove the DRM.

If you install any plugins correctly the server will use them automatically. As for the dedrm plugin in particular, I have no idea, I dont use that plugin. Check that you are trying to add the actual plugin zip file not the wrapper zip file. And remember that dedrm has been superseded by nodrm

I have reinstalled the plugin again, and this time it seems to be installed:
Plugin added: DeDRM (10, 0, 3)

And the conversion works.
@kovidgoyal, I have used the correct plugin in GitHub its called nodrm / DeDRM

I have no idea what when wrong the first time
Thank you all
