# Instructions for installing Pi-hole 4.2 on UniFi CloudKey Gen 1 (UC-CK) running firmware 0.13.6
# Pi-hole will need to be completely re-installed after every FW update or if CloudKey is reset to defaults.

# Verify UC-CK is running firmware v0.13.6 (or later) before installing Pi-hole. If not, do:
ubnt-systool fwupdate https://dl.ubnt.com/unifi/stage/cloudkey/firmware/UCK/UCK.mtk7623.v0.13.6.7ad551e.190225.0939.bin

# UC-CK firmware v0.13.6 downgrades UniFi Controller to 5.10.17. Upgrade to 5.10.19 with:
cd /tmp
wget https://dl.ubnt.com/unifi/5.10.19/unifi_sysvinit_all.deb
dpkg -i unifi_sysvinit_all.deb
