    Pi-hole v5.1.2 Web Interface v5.1.1 FTL v5.2
    Cloud Key firmware UCKG2.apq8053.v1.1.13.818cc5f.200430.0938

Instructions


Change all your networks to use 1.1.1.1 or some other upstream DNS so that you still have DNS resolution working once the firmware upgrade completes

Alternately, setup all your networks to have a secondary upstream DNS. While not ideal, will help with a seamless update process


Upgrade the firmware on the cloud-key


Briefly enable system-resolved (if not cloud-key will not be able to resolve DNS)
sudo systemctl start systemd-resolved

#(Answer Y to replace the files as keeping the existing will point to 01-pihole.conf which does not work until pi-hole is installed)

# dnsmasq install will fail to start dnsmasq so lets resolve that

Fix the php issue (valid only on older versions). If HTTP_HOST is not found, ignore this section.

/var/www/html/pihole/index.php

change
$serverName = htmlspecialchars($_SERVER["HTTP_HOST"]);

to
$serverName = htmlspecialchars($_SERVER["SERVER_ADDR"]);
