Installation guide built on Debian 12.
This guide doesn't cover upgrading from lower versions of Unifi or any of its dependencies.
Obtain v1.1 of libssl from the Debian.org FTP server
wget https://ftp.debian.org/debian/pool/main/o/openssl/libssl1.1_1.1.1w-0+deb11u1_amd64.debWe'll install MongoDB v4.4 for compatibility reasons. Good job Ubiquiti /s.
Add the v4.4 repo
echo "deb [ signed-by=/usr/share/keyrings/mongodb-server-4.4.gpg ] http://repo.mongodb.org/apt/debian buster/mongodb-org/4.4 main" | tee /etc/apt/sources.list.d/mongodb-org-4.4.listAdd the repo key
curl -fsSL https://www.mongodb.org/static/pgp/server-4.4.asc | gpg -o /usr/share/keyrings/mongodb-server-4.4.gpg --dearmorInstall MongoDB v4.4
apt install mongodb-orgVerify mDB version
mongod --versionInstall Java 17
apt install openjdk-17-jre-headlessInstall package dependencies
apt install ca-certificates apt-transport-httpsAdd the Unifi repository and its key
echo 'deb [ arch=amd64 signed-by=/etc/apt/keyrings/unifi-repo.gpg ] https://www.ui.com/downloads/unifi/debian unifi-8.0 ubiquiti' | tee /etc/apt/sources.list.d/100-ubnt-unifi.list
curl -fsSL https://dl.ui.com/unifi/unifi-repo.gpg | gpg --dearmor -o /etc/apt/keyrings/unifi-repo.gpgUpdate and install Unifi Controller
apt update
apt install unifiTo access the Unifi Controller, navigate to https://[IP-or-hostname]:8443
I've created a custom firewalld service because of the port requirements Unifi has.
Create a new xml file at /etc/network/unifi-service.xml with the following contents Remove the comments for ports as you need them.
<?xml version="1.0" encoding="utf-8"?>
<service>
<!--<port port="53" protocol="tcp"/>-->
<!--<port port="53" protocol="udp"/>-->
<port port="3478" protocol="udp"/>
