Pi-Hole Notes

172.16.0.5 - gadget 172.16.0.6 - gizmo 172.16.0.10 - VIP

Upgrade to latest Raspbian⚑

Updating OS: 

sudo apt update
sudo apt full-upgrade

Error: 

E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable'

Fix here 

sudo apt-get update --allow-releaseinfo-change

Despite various sites saying it's not possible, I tried taking a shortcut and did a full upgrade instead of total install from scratch. So far, so good, after 3 weeks.

Add deb https://archive.raspberrypi.org/debian/ bullseye main to /etc/apt/sources.list

Reset Pi-Hole passwd⚑

pi@gizmo:~ $ sudo pihole -a -p
Enter New Password (Blank for no password):
  [✓] Password Removed

Update Pi-Hole⚑

pi@gizmo:~ $ pihole -up

Gravity-Sync⚑

(for replication) I set this up years ago and pretty much just followed this guide. There are 2 Pi-Holes and VIP that is used for DNS. When one goes down, the other takes over at the VIP.
