public key is not available | apt-get update

Teman-teman linux pernah mengalami hal seperti ini, pada saat apt-get update ????

W: GPG error: http://ppa.launchpad.net oneiric Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6AF0E1940624A220

Jangan kawatir deh, linux it`s easy n fun :D
langsung ada paste code berikut pada terminal teman2

apt-key adv --keyserver keyserver.Ubuntu.com --recv-keys PASTE_NO_PUBKEY

PASTE_NO_PUBKEY = paste code NO_PUBKEY nya, pada kasus di atas NO_PUBKEY nya 6AF0E1940624A220

jadi seperti ini :

 apt-key adv --keyserver keyserver.Ubuntu.com --recv-keys 6AF0E1940624A220

uda deh :), gampang kan,....
coba apt-get update lagi pasti mulus :p
