Having trouble update after installing all

[BlueBoy74]

I’m running Kali iOS on a iPhone 11 18.2.1 ishapp. Running great here and there may run into a problem that is solvable but this is the newest.

Hit:2 http://old.kali.org/kali 2019.2 Release
Ign:3 http://old.kali.org/kali 2019.2 Release.gpg
Reading package lists... Done
E: The repository 'http://old.kali.org/kali 2019.2 Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Any help
Thank you
