You need to install a new debian GPG key use this little script, like this:

mybox ~ # cd /usr/local/bin

and ...

mybox ~ # chmod a+x /usr/local/bin/apt-install-key

mybox ~ # cat /usr/local/bin/apt-install-key
#!/bin/sh
echo Getting Key $1
gpg --recv-keys --keyserver hkp://pgp.mit.edu $1
gpg --armor --export $1 | apt-key add -
echo =============[FINGERPRINT]==============
gpg -v --fingerprint
echo ========================================
echo done

run like:

mybox ~ # apt-install-key 010908312D230C5F

If you don't have the security software you can install it as follows:

mybox ~ # apt-get install gnupg
