Nop, I use apt-0.5.15cnc5-0.fdr.10.1.i386 version and this is my /etc/apt/apt.conf
// User customizable configuration
RPM
{
// Uncomment to disable GPG-signature checking for packages
// GPG-Check "false";
// Uncomment to prevent kernel being handled along with (dist-)upgrade
// Upgrade-Kernel "false";
// Uncomment to hold packages with modified config files in (dist-)upgrade
// Preserve-Config "true";
};
// Options for the downloading routines
Acquire
{
// Retries "1";
// http::Proxy "http://user

assword@proxy-server.domain.tld

ort/";
// http::Proxy "http://proxy-server.domain.tld

ort/";
};
// Automatically written by your friendly first-time druid...
Apt::State::FirstRun "false";
So, if you don't want apt to check the gpg keys, you have to edit your /etc/apt/apt.conf and comment this line GPG-Check "true"; or delete // at the beggining, like this:
// GPG-Check "true";
or changing the parameter true x false
GPG-Check "false";
Thank you mhelios anyway !!!
