upgrade

I am installing 13.04 into a VirtualBox machine.

After installing, I receive this error after sudo apt-get update:

Ign http://archive.ubuntu.com raring Release
E: Erro GPG: http://archive.ubuntu.com raring Release: the following signatures were invalid: NODATA 1 NODATA 2

I have already tried:

Install minimal server version;
Install 12.04 desktop version;

Everything gives me the same error.
