Tota obrigado pela ajuda. Consegui resolver seguindo esse link http://www.vivaolinux.com.br/artigo/Resolvendo-o-problema-do-aptget-NO_PUBKEY

Em resumo, dois comandos:

# gpg --keyserver subkeys.pgp.net --recv (sua key)   
No lugar de (sua key) coloquei 13AA04366D36B2F8, que é a numeraçao que aparece no final do erro

# gpg --export --armor (sua key) | sudo apt-key add -
Novamente substitui o (sua key) pelos numeros 13AA04366D36B2F8

Problema resolvido. Obrigado a todos.
