Updates have stopped authenticating

[kentcb]

I am running Intrepid. Sometime last week I started getting errors when attempting to apply updates. If I force the Update Manager to check for updates, I get this:

W: GPG error: http://ppa.launchpad.net intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 43C0AFF0D7FAE680

If I click the Install button I am told that XMBC-related packages cannot be authenticated.

Do I need to worry about this? Should I just install anyway?

Thanks,
Kent

You should be ok to install. You can add the new key by opening a terminal and

gpg --keyserver keyserver.ubuntu.com --recv 43C0AFF0D7FAE680

gpg --export --armor 43C0AFF0D7FAE680 | sudo apt-key add -

then

sudo apt-get update

Here's a script, it can fix ppa links and get gpg keys:
