You sent me this link :
https://www.mobileread.com/forums/sho...d.php?t=225030
With the advice to use the last version.
I didnt saw the thread was from 2013 and I confused between Kindle 2 and Kindle Paper White 2.
So initialy I was using all the good packages.
And it didn't work.
I think the Python K2 version didn't install and I re install the "Update_linkss_0.24.N_install_pw2"
I used this clear install advices : "http://www.ereader-palace.com/4-must-have-plugins-to-install-after-jailbreaking-kindle/"
So the question remains, what is wrong ?
The error under KUAL is :
SW failed to process cover
