Yesterday I got tired of the nagging “Update Available” on my Ubiquiti Video NVR so I went through the upgrade process in the web GUI. It failed with Error 400. I tried several times, several browsers, same error. I then went to the CLI and attempted an apt-get update, apt-get upgrade, etc and no joy getting the new version of Unifi Video.

I then downloaded the latest version and attempted to install with dpkg and got this:

In addition, it removed my previous version and so my Ubiquiti NVR was dead in the water. I did some Googling and found many, many posts with all kinds of fixes, none of which worked. I began getting upgrade remorse, fearing I had forced too many upgrades and thoroughly corrupted my OS. Ugh. I then found this post and copy/pasted it verbatim.

apt-get clean
rm /etc/apt/sources.list
echo 'deb http://archive.debian.org/debian/ wheezy main contrib non-free' >> /etc/apt/sources.list
echo 'deb http://archive.debian.org/debian/ jessie-backports main' >> /etc/apt/sources.list.d/openjdk.list
echo 'deb http://archive.debian.org/debian/ jessie main' >> /etc/apt/sources.list.d/openjdk.list
apt-get update -o Acquire::Check-Valid-Until=false
apt-get install -y -t jessie-backports openjdk-8-jre-headless
rm /etc/apt/sources.list.d/openjdk.list
apt-get update

Whala! All of these commands actually ran without much error other than warnings and boom, Unifi loaded. The issue was my Java version and Wheezy was reluctant to upgrade past version 7, hence my earlier issues.

So, if you want to upgrade to version 3.10.5, expect some issues but this worked for me. Good luck!
