You have an old version of the kali-archive-keyring package (2015.2) which contains our old archive key which expired today. We pushed (a bit late) an updated key one week ago in the version 2018.1 of the kali-archive-keyring package. You can manually install this package:

# wget
# dpkg -i kali-archive-keyring_2018.1_all.deb

And then it should be back to normal. An alternative solution is to fetch the updated key directly and make it available to APT:

# wget -O /etc/apt/trusted.gpg.d/kali-archive-key.asc

(you can delete /etc/apt/trusted.gpg.d/kali-archive-key.asc after having completed an upgrade that installed the new kali-archive-keyring)

Sorry for the inconvenience, now you can go back to enjoy your Kali system! ;-)
