This seems like an OS / permission issue, not related to Pi-hole.

apt requires sudo to run, i.e. you should use sudo apt-get update.

[I apologize for my novice understanding. Here is what happened next.]

pi@pihole:~ $ sudo apt-get update
Hit:1 http://archive.raspberrypi.org/debian buster InRelease
Get:2 http://raspbian.raspberrypi.org/raspbian buster InRelease [15.0 kB]

E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

You would be better served posting in the RaspberryPi forums as that is where your issue is. It’s not a PiHole issue.

Please consider to familiarise yourself with your OS's package manager apt: That's still an issue with updating your OS rather than Pi-hole.

Answering [y]es to that question or running sudo apt-get update --allow-releaseinfo-change should allow your OS to reflect that change and continue.

Until the apt update process (controlled by the OS) completes, the Pi-hole installer/updater will not continue.

After you get the apt update problem resolved at the OS level, re-run the Pi-hole updater.

Many thanks to all responders; following the advice provided allowed the OS to update successful and then the pi-hole update succeeded!

This is a great community.
