Error when convert epub to kepub

[Freddec]

Hi all
First, excuse me for my very bad english (I'm french)

OS: Win7 (64 bit)
Calibre: 2.14 (64 bit)
Input File format; epub
Output File format: kepub

With this new version (i've juste upgrade), when i select "kepub" in ouput i've this message:
"ImportError: No module named PyQt4"

This, is the text I've in the Detail windows

calibre, version 2.14.0
ERREUR : Exception non gérée: <b>ImportError</b>:No module named PyQt4

If I clic on the "OK" button of the convert windows then I have this error
"AttributeError: 'MetadataWidget' object have no attribute 'opf_file' "

This is the text I've in teh detail windows:

I hope some one could help me
It seems that there is no problem to convert from epub to another format (epub -> mobi for example)

thanks

did you update your Kobo Utilities Plugins to the latest?

That error is typical for a pre Calibre 2.x version of the PI

[Freddec]

yes, i've upgrade Calibre and Kobo utilities plugin at the same time

The Kobo utilities version is 1.8.5 (2014 dec 13)
I've unintsall et ré-install, but this the same problem

I've also tr with the 32bit version

Do you now where i'could find a previous version (i didn't saw them on calibre website)

Thanks

Kobo Utilities have nothing to do with the conversion to kepub format; that's handled by either [Device Plugin] Kobo Touch Extended Driver or [Conversion Output] KePub Output Plugin depending on how you want to do the conversion (on the fly as it's sent to the device, or on demand and stored in the library).

It looks like, as the OP is selecting kepub as output, he's using the coversion plugin. Furthermore, I think the drivers are automatically updated when calibre is updated, but plugins aren't. So, perhaps, he should update that plugin.

hi,

I've downgrade to 2.11 and to 2.8 version with no result.
I've uninstall/reinstall all kobo plugins with no more result

Even when all kobo plugins are uninstalled, i can have the choice to convert to kepub (so this option do not come with plugin's, but is directly inside Calibre). But I always have the same error :-(

Re

I've reinstall the the "Conversion Output KePub" from the zip file in Calibre 2.8 version : https://www.mobileread.com/forums/sho...d.php?t=220565

test OK

I've also re-update Calibre to 2.13 and test again to convert epub to kepub, it's work fine !

I don't know/anderstand why it have crashed !

Thank's PeterT (and other) for your help
