Key Update Does Not Resolve Expired Key

[Bill Diehl]

Debian Mozilla Team:

I have installed the pkg-mozilla-archive-keyring package as instructed
but still get the expired key error. Please help!

# apt-get update
Get:1 http://mozilla.debian.net lenny-backports Release.gpg [828B]
Ign http://mozilla.debian.net lenny-backports/iceweasel-3.6 Translation-en_US

W: GPG error: http://mozilla.debian.net lenny-backports Release: The
following signatures were invalid: KEYEXPIRED 1321788755
W: You may want to run apt-get update to correct these problems


Why do I still get the above error when the below looks correct?

# gpg -k
/root/.gnupg/pubring.gpg
------------------------
pub   4096R/06C4AE2A 2010-11-20 [expires: 2012-11-14]
uid                  Debian Mozilla team APT archive
<pkg-mozilla-maintainers at lists.alioth.debian.org>


Why is it that the below still shows the expired key?

apt-key list
/etc/apt/trusted.gpg
--------------------
pub   4096R/06C4AE2A 2010-11-20 [expired: 2011-11-20]
uid                  Debian Mozilla team APT archive
<pkg-mozilla-maintainers at lists.alioth.debian.org>


The the best of my knowledge, I have followed the instructions to
update the Debian Mozilla Team's APT key but I still get the key
error.

I have spent hours trying to resolve this issue myself without success.

Please, PLEASE, direct me to a resource that will tell me how to make
the new key work properly on my Lenny system.

Thank you - THANK YOU!!!
