GPG error: http://extras.ubuntu.com natty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192
I think I selected to install things from extras.ubuntu.com when I used the expert mode installer, but I got the above error when doing apt-get update. How do I fix this?
gpg --keyserver keyserver.ubuntu.com --recv 3E5C1192
gpg --export --armor 3E5C1192 | sudo apt-key add -
sudo apt-get update
This could be a solution. From
