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.
