Comment 6 for bug 645110

I'm receiving this error and ubuntu-extras-keyring v 2010.09.27 IS installed. I attempted to reinstall but it still fails.

+ I installed maverick to disk with updates and enable repo from the Maverick LiveCD

After installing and rebooting doing an update yields:

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DB141E2302FDF932

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/maverick/Release

W: Some index files failed to download, they have been ignored, or old ones used instead.
