I have the same error with this source list, I cant understend why

## Kali Security updates
deb http://security.kali.org/kali-security kali/updates main contrib non-free

## Kali
deb http://http.kali.org/kali kali main contrib non-free

## Kali-dev
deb http://http.kali.org/kali kali-dev main contrib non-free

On my ends everything works good try editing your source file and adding what I have

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL Binary 20130327-18:35]/ kali contrib main non-free

#deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL Binary 20130327-18:35]/ kali contrib main non-free

## Security updates
deb http://security.kali.org/kali-security kali/updates main contrib non-free
deb http://http.kali.org/kali kali main contrib non-free

I have tried several combinations of sources and still get the same error, even with only

deb http://http.kali.org/kali kali main contrib non-free
deb http://security.kali.org/kali-security kali/updates main contrib non-free

Whats wrong?

For some reason i was told to write this on bash

echo 'APT:efault-Release "testing";' >> /etc/apt/apt.conf

that was the problem, I just delete that line in the file.
