GPG error when pulling updates from security.debian.org

Did an aptitude update on a Debian Lenny box and got:

W: GPG error: http://security.debian.org lenny/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AED4B06F473041FA
W: You may want to run apt-get update to correct these problems

According to Debian News, the GPG key expired:

This key rollover is a normal maintenance task and was started in August 2010. For security reasons Debian's archive signing keys regularly expire after three years.

Solution:

sudo aptitude install debian-archive-keyring

---8<---
The following packages will be upgraded:
  debian-archive-keyring 
1 packages upgraded, 0 newly installed, 0 to remove and 59 not upgraded.

Now the "NO_PUBKEY" error is gone and I can go one with installing my updates.
