Kali KEYEXPIRED 1425567400 KEYEXPIRED 1425567400 KEYEXPIRED 1425567400

While updating Kali Linux, I got a rather strange message:
KEYEXPIRED 1425567400 KEYEXPIRED 1425567400 KEYEXPIRED 1425567400

Somehow that indicate that the keys used for GPG is likely to be expired. 

I dig a bit and found that the way to update the keys is as follows:
apt-key adv --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6

Now your Kali should be updating normally again!
BTW, Kali v1.1.0a is out. Maybe its a good time to reinstall the latest version!
