If you don’t update Kali regularly, then your archive-keyring package is outdated, and you’ll get key mismatches when working with Kali Linux repositories.
So when one try to execute command sudo apt-get update will get error as below:
W: Failed to fetch http://http.kali.org/kali/dists/kali-rolling/InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository

How to apply fix:
wget -q -O - https://archive.kali.org/archive-key.asc | apt-key add
