Obok DeDrM plugin not working in Calibre 6.17.0?

[ZenmasterJ]

Question / bug report

My OBOK plugin is installed successfully from the latest DeDRM release (10.0.3). The icon is on the top of my calibre screen.

When I press the icon, I get the following error message.

calibre, version 6.17.0 ERROR: Unhandled exception: AttributeError:type object 'QTableWidgetItem' has no attribute 'UserType'

Running Windows 10. I am trying to open books downloaded to my Kobo App for PC. I can add the books by putting a .kepub at the end of the generic file name from the Kobo app folder, but cannot open them (Calibre says they contain DeDRM). I know that I need the Obok plugin to deDRM these files, but when I click on the Obok plugin icon in calibre, I get the above error message. Got the same error message in Calibre 6.08 as well before I just updated Calibre to 6.17.

Which version of Calibre are you running?

6.17

Which version of the DeDRM plugin are you running?

v10.0.3

If applicable, which version of the Kindle software are you running?

No response

Log shows that you still have 7.2.1 plugins. For calibre 6, you need 10.0.3.

I have installed the obok plugin from the DeDRM 10.03 package. In Calibre, from the Preferences tab, I go to Advanced then Load Plugin from File, and then choose the OBOK zip file in the DeDRM 10.03 package. That OBOK plugin still reads as v 7.2.1. How can I download the 10.03 OBOK plugin?

[ElleKayEm]

Make sure you are really browsing to the correct folder for 10.0.3 and restart calibre after loading it.

I'm hoping I can jump on this thread, as I'm having a similar issue. I have books purchased via Kobo that I would like to manage in Calibre. I just installed Obok DeDRM v 10.0.3. I added the Kobo serial number and the path to the Kobo Desktop App downloads.

If I run Obok in Calibre with the Kobo connected, it appears to see (only) the books that are on the device. However, trying to add a book from that list gives me "[title] not added because it couldn't be decrypted."

If I disconnect the device and run Obok again, I get the message below. I have five books in the folder at the path I defined when configuring Obok. I left one without a file extension, added .epub to one, and added .kepub to the other three.

calibre, version 6.19.1 ERROR: Obok DeDRM v10.0.3:

Could not find Kobo Library

Windows/Mac: do you have Kobo Desktop installed?

Windows/Mac/Linux: In case you have an Kobo eInk device, connect the device.

Obok also doesn't appear to run against books that I pull into Calibre manually:

If I drag and drop an .epub version into Calibre, it shows some of the metadata and I can open it, but isn't readable.

If I drag and drop a .kepub version into Calibre, I get the following when I try to open it:

Any recommendations? I appreciate your help!

For Obok, you only use Obok to import the books. Alternatively, you can download the Adobe DRM versions from the Kobo website using ADE and then use the DeDRM plugin.

[calyst1978]

Okay, but the import isn't working, unless I'm doing it wrong. The first two examples I gave would have been using Obok to import, wouldn't they?

[calyst1978]

I think I figured it out, although this would be way easier if it could pull from the device instead of having to download from the desktop app.

I had to map the directory one level higher and remove the file extensions that I added. I'll keep working with this. Fingers crossed!

[ElleKayEm]

I've never had to configure anything when using Obok. It just works with either my Kobo ereader or Kobo Desktop. I seen others sometimes have issues like yours though. I don't know what the trick is.
