apt ignores apt.conf settings

[Maxim Vexler <hq4ever@gmail.com>]

Hi debian,

It's seem that I have an especially stubborn apt on my hands.
Each of the settings I put in my /etc/apt/apt.conf are getting
blatantly ignored by apt.

# cat /etc/apt/apt.conf
APT::Default-Release "testing";

APT::Periodic::Update-Package-Lists=1;
APT::Periodic::Download-Upgradeable-Packages=1;
APT::Periodic::AutocleanInterval=30;

APT::Get::AllowUnauthenticated 1 ;

# apt-show-versions apt
apt/testing uptodate 0.6.43

As you can see, I have setted the "AllowUnauthenticated" option, as
mentioned in [1] but I still receieve the "Untrusted package" 
warnings.

Also, to my knowladge, no periodic downloading or updating of anything
is occuring.


Help?
Thank you for reading.
