This is a guide on how to install mFi Controller, for anyone still using it. mFi has not received security updates since 2016.

If you are looking for an mFi replacement, Ubiquiti is developing new products in this space including UniFi LED and UniFi SmartPower.

Editor's note: UniFi LED has since been discontinued.

Download Debian 7

Download the Debian 7 netinst CD image from the Debian wheezy installer page.

Install Debian

Configure the package manager

On the "Configure the package manager" step, rather than selecting a nearby country, scroll to the top and select "enter information manually".

Enter the Debian archive mirror

Enter "archive.debian.org" as the mirror hostname.

Acknowledge the security updates warning

You will receive an error that there won't be any security updates from Debian.

Install mFi Controller

Once the installation is complete, log in as root or use su to become root, then run these commands to install mFi Controller:

apt-get update -y
echo "deb http://dl.ubnt.com/mfi/distros/deb/ubuntu ubuntu ubiquiti" >> /etc/apt/sources.list
