These instructions were validated for unifi controller v5.7.23 being installed on Ubuntu 18.04 LTS.

• Start with clean install of Ubuntu 18.04 on Oracle VirtualBox v5.2.12.
• Install java 8 using websiteforstudents.com or tecadmin.net.
• If desired, install the firewall GUI administration tool from Software Center (apt install gnome-software)
• Review the Unifi ports to open
  • As of 14 July 2018, add TCP ports 8080, 8443 and UDP 3478 to public/permanent
  • Note: Enabling Cloud Access and accessing the controller via https://unifi.ubnt.com instead does not require opening 8443, and is safer since no direct Internet access is permitted to your controller's management.

$ sudo -s
$ cd /root
$ mkdir downloads

Download the latest controller software from https://www.ubnt.com/download/unifi/. It will be named something like "unifi_sysvinit_all.deb".

apt-get install ./unifi_sysvinit_all.deb

Fix /usr/bin/mongod noted in https://websiteforstudents.com/how-to-install-oracle-java-jdk8-on-ubuntu-16-04-17-10-18-04-desktops/
