Tested ONLY on Orangepizero2_3.0.4_ubuntu_jammy_server_linux5.16.17 firmware based Ubuntu for Orange Pi Zero 2.

Most likely for other firmware versions based on Ubuntu, including other Orange Pi controllers, this instruction is also suitable .. The main thing is that the controller be based on an arm64 processor. But I can't guarantee anything! Everything is at your own risk. I am not responsible!

1. Download & install latest 64 bit version based on Ubuntu of Orange Pi Zero 2 to new sd card of your choice from the link below:

https://drive.google.com/drive/folders/1ohxfoxWJ0sv8yEHbrXL1Bu2RkBhuCMup

2. Download and install libssl1. Need for MongoDB. Repository Orange Pi not uncluded this pakage.

wget http://ports.ubuntu.com/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_arm64.deb
sudo apt install /root/libssl1.1_1.1.0g-2ubuntu4_arm64.deb

3. Download and install version 4.4.11 of MongoDB mongodb-server from https://www.mongodb.com/download-center/community/releases/archive

wget https://repo.mongodb.org/apt/ubuntu/dists/focal/mongodb-org/4.4/multiverse/binary-arm64/mongodb-org-server_4.4.11_arm64.deb
sudo apt install /root/mongodb-org-server_4.4.11_arm64.deb

4. Mongodb server would normally be run as a service by doing the following commands  

sudo systemctl daemon-reload
sudo systemctl enable mongod

sudo systemctl start mongod

In this case not required, as Omada controller starts the server as required.
   
5. Check that curl is installed

apt list curl

6. Install openjdk-8-jre

sudo apt install openjdk-8-jre-headless

7. Install jsvc
sudo apt install jsvc

8. Download and install latest version Omada SDN controller:

wget https://static.tp-link.com/upload/software/2022/202207/20220729/Omada_SDN_Controller_v5.4.6_Linux_x64.deb
sudo apt install /root/Omada_SDN_Controller_v5.4.6_Linux_x64.deb

If all went well the controller should start and you should get the following message

Install Omada Controller succeeded!

Omada Controller will start up with system boot. You can also control it by [/usr/bin/tpeap].
