Try this as root:
# gpg --recv-keys 4D270D06F42584E6

# gpg --export 4D270D06F42584E6 | apt-key add -
That should download the key from a public keyserver and then the second command adds it to apt. You may need to specify a keyserver if the default doesn't work. There are several public ones available.

thx, it works well, but I've found other way of life:
# apt-get install debian-keyring debian-archive-keyring
# apt-key update

Since I see that this thread was recently resurrected, and even though cccc answered their own question, I thought that I would add that as of Debian 7, you can simply open the Synaptic package manager and choose 'Mark all upgrades'.

Although the debian-keyring selection isn't checked, the debian-archive-keyring is shown as an upgrade, and once done upgrading this does fix the issue.

Cccc, I was using your solution for a long time, thank you for that
