What should I have to do to resolve this problem ???
Thank you!

You need to double check your /etc/apt/sources.list

From the sounds of it, you have the following uncommented.

Code:

---

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL Binary 20140108-18:08]/ kali contrib main non-free
#deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL Binary 20140108-18:08]/ kali contrib main non-free
