[clug] Debian (Lenny) upgrade woes

[Felix Karpfen]

My latest "apt-get update/upgrade" routine gave the following warnings:

[root at carrot ~]# apt-get update

SNIP

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**

As a perennial Newbie, I find the second warning to be unhelpful.  

I have received a "security advice" (date 9 Feb), that - in accordance 
with standard procedure - the "Archive Signing Key" will be changed, but 
the relevant URLs:

http://packages.debian.org/debian-archive-keyring; and 
http://lists.debian.org/87d3t3as2k.fsf@gkar.ganneff.de

proved to be equally obscure.

All advice will be gratefully received.
