As of March 20th, 2019  new UVC-NVR and UVC-NVR-2TB or those that have been factory reset, and are on version 3.9.12 or earlier, will need to follow a manual update process in order to install version 3.10.0 or higher. Windows users, UAS-XG users, and custom linux installations are NOT affected.

Follow these steps for a manual upgrade:

  1. Enable SSH on your UVC-NVR
  2. Open a shell session (SSH) to the NVR appliance. Need help with SSH? See our Related Articles below.
  3. Run the following commands one at a time in your SSH terminal:
service unifi-video stop;
apt-get clean;
rm /etc/apt/sources.list;
rm /etc/apt/sources.list.d/security.list;
echo 'deb http://archive.debian.org/debian/ wheezy main contrib non-free' > /etc/apt/sources.list;
echo 'deb http://archive.debian.org/debian-security/ wheezy/updates main' > /etc/apt/sources.list.d/security.list;
apt-get update -o Acquire::Check-Valid-Until=false;
apt-get upgrade -y -o Acquire::Check-Valid-Until=false;
