apt-get failed to fetch errors...

I'm seeing the following errors running 'apt-get update'. Not sure why. /var/log/apt-cacher/error.log shows no errors.

apt-get update missing GPG key

I was seeing the following error when running "Check" on the update-manager, or 'apt-get update':

GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 248DD1EEBC8EBFE8

Answer, kudos to Gentoo Blog:

% gpg --keyserver subkeys.pgp.net --recv 248DD1EEBC8EBFE8
gpg: requesting key BC8EBFE8 from hkp server subkeys.pgp.net
gpg: key BC8EBFE8: public key "Launchpad PPA for Network-manager" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)
% gpg --export --armor 248DD1EEBC8EBFE8 | sudo apt-key add -
OK
