Q. I don’t trust this new key! Are you really Kali Linux?
A. The new key is signed by some developers from the Kali team, and the signatures are available on the Ubuntu OpenPGP keyserver. You can check it out at https://keyserver.ubuntu.com/pks/lookup?search=827C8569F2518CC677FECA1AED65462EC8D5E4C5&fingerprint=on&op=index.
I hope those developers have verified in person that the key custodian is not under duress!
