no_pubkey apt-get update
I just installed a virtual machine using Ubuntu linux and got NO_PUBKEY error messages when tried to update my Ubuntu installation using "apt-get update" command. To fix this you'll need to install some gpg key:
gpg --keyserver wwwkeys.eu.pgp.net --recv 9AA38DCD55BE302B gpg --export --armor 9AA38DCD55BE302B | apt-key add -
