In this post I will show you how to install Unifi Controller on Debian 10 Buster.

Install requiremens

apt install apt-transport-https ca-certificates wget dirmngr gnupg gnupg2 software-properties-common multiarch-support

Install MongoDB

Unifi Controller requires a MongoDB from 2.4 to 4.0. The stander version of MongoDB to Debian 10 is 4.4 and 4.0-s requiremens conflicts with the Debians main libs. So we need to install MongoDB 3.4.

wget -qO - https://www.mongodb.org/static/pgp/server-3.4.asc |  apt-key add -
echo "deb http://repo.mongodb.org/apt/debian jessie/mongodb-org/3.4 main" | tee /etc/apt/sources.list.d/mongodb-org-3.4.list

We need an old version of libssl to run MongoDB 3.4:

wget http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u12_amd64.deb
dpkg -i libssl1.0.0_1.0.1t-1+deb8u12_amd64.deb

Install Java 8

wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/

apt update
apt install adoptopenjdk-8-hotspot

java -version

nano /etc/profile
export JAVA_HOME="/usr/lib/jvm/adoptopenjdk-8-hotspot-amd64"
source /etc/profile

echo $JAVA_HOME
