Hello,
first of all I want to thank you for this great software, which is possible to run on a small device like my raspberry pi 2 b alongside with other services.
Unfortunatly I ignored the top rule "Never touch a running system" and tried to major update my pihole v5 setup to v6 and for now nothing is running anymore.
Because I dont't want to make a fresh install with newest raspbian version and broke the other sevices which are running for 5 years now as well, I tried to get the an old version of pi-hole. But, as I understand it correct, this is not intended neither possible.
My next approach was to completly uninstall / clean pihole from my system and install pihole in a docker container which should be more comfortable.
Because I don't found explanations with a internet search I have made this post.
Here is the lsb_release output:

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.
The intent of this script is to allow users to self-diagnose their installations. This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected. Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.
NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.
