I found a solution to my problem.

# Retrieve the ubuntu key with wwwkeys.eu.pgp.net, store it in my keyring
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 437D05B5
# Add the retrieved key along with other existing keys
sudo apt-key add ~/.gnupg/pubring.gpg
# apt-get update without cache to force the use of the newly added key
sudo apt-get update -o Acquire::http::No-Cache=True

The last step seems essential.  I tried resetting back to the defaults
with synaptic (thanks to Bjørn Ingmar Berg).  It did not immediately
clear the warning until I purged the cache.


  I have accidentally deleted an apt-key.  Now I am getting NO_PUBKEY
  warnings when I do "apt-get update".  
  I think I can do "wget -q http://URL-key.gpg -O- | sudo apt-key add -"
  to add them back manually.  But I can't seem to figure out WHERE to
  look for the public keys.  I have googled and searched the ubuntu
  packages sites to no avail.  From apt-get's warnings I need the public
  keys from two sources: "2EBC26B60C5A2783" and "40976EAF437D05B5" (edgy
  default key I think).
