Install Unifi controller on Ubuntu

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 or
  • If desired, install the firewall GUI administration tool from Software Center (apt install gnome-software)
    • 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 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 and then install the latest controller software from It will be named something like “unifi_sysvinit_all.deb”:

apt-get install ./unifi_sysvinit_all.deb

Fix /usr/bin/mongod as noted in

$ cd /usr/bin
$ sudo -s
$ mv mongod mongod.bin

Replace mongod with the following:

cleaned_args=$(echo $* | sed -e 's/--nohttpinterface//')
exec /usr/bin/mongod.bin ${cleaned_args}

Fix permissions:

$ chmod +x mongod

Restart services:

$ systemctl restart unifi
$ systemctl status unifi

If desired, cat /var/log/unifi/server.log and mongod.log to ensure no errors are reported.

Now you may use the VM or another machine to access the webpage on the virtual machine's IP (https://VM_IP_ADDRESS:8443/login)

If the AP can't be found, do the following:

ssh to AP IP address and login as ubnt, using the default password ubnt. You may need to factory reset the controller if the password has been changed.

Tell the AP where the controller software is running (IP below is VirtualMachine noted above):


Then login to the controller and adopt the AP.
