ciao a tutti

uso ubuntu 7.04
mi sono scaricato kerneler
l'ho scompattato nella home , eseguo :
codice:
ettore@portatile:~$ bash programmi/kerneler_0.19a_alpha/kerneler
mi compare :
codice:
It's necessary to install 
- dialog 
- kernel-package  
to run Kerneler correctly    
Do you want to do it now?
 y  
sudo  found! Do you want to use sudo to manage super user privileges? (Yes/no) 
y 
Insert sudo password 
Password:
inserisco la password e mi dice :
codice:
Error with kerneler directory. . . Now it will be reconfigured! Press ENTER to continue
poi va in palla ovvero continua una linea
