Installing Ubiquiti's Unifi controller on Ubuntu is fairly straight forward. The first step is to install the Unifi controller with the following commands:
deb http://www.ubnt.com/downloads/unifi/debian stable ubiquiti
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 06E85760C0A52C50
sudo apt-get update
sudo apt-get install unifi
If you have Oracle Java installed on Ubuntu there is a good chance that the Unifi controller will fail to locate JAVA_HOME. To solve this follow these steps:
Step 1
echo $JAVA_HOME
You should get the following path returned:
/usr/lib/jvm/java-8-oracle
Step 2
Next, you need to edit the unifi.init script with the following command:
sudo nano /usr/lib/unifi/bin/unifi.init
At the bottom of the set_java_home() method ensure that JAVA_HOME is as follows:
JAVA_HOME=/usr/lib/jvm/java-8-oracle
This directory pasted here is of course dependent on what directory was echoed back in step 1.
Step 4
Restart the unifi controller and check its status with the following commands:
sudo systemctl restart unifi
sudo systemctl status unifi
The status command should yield output similar to the following:
![""]("__GHOST_URL__/content/images/2017/06/unifi.png")
Step 5
You are now able to access the admin panel by inputting the following in your web browser:
