Some little informations about debian keyrings, just for archive propose...

If you get something like that:

W: GPG error: http://security.debian.org etch/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B
W: GPG error: http://ftp.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B
W: GPG error: http://updates.xensource.com etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 841D6D8DFE3F8BB2
W: You may want to run apt-get update to correct these problems

you have to update your keyrings.

For the debian mirrors:
apt-get install debian-archive-keyring

And for the xen mirrors (current v 5.5):
wget -q http://updates.vmd.citrix.com/XenServer/5.5.0/GPG-KEY -O- | apt-key add -
