What is the easiest way to resolve apt-get BADSIG GPG errors?
I have a Ubuntu Server VM running 12.10 and functioning as a Minecraft server. I tried to run updates on it today and am getting an error the singature for quantal-backports doesn't match. I get an invalid signature on that, the key is 4097EAF437D05B5
or at least that's what the error shows.
Is there an easy way to resolve this?
Thanks
