Introduction

This article mainly introduces the process and key considerations for reinstalling the Milesight OpenVision Server system and the Nx Witness Server.

Precautions

Reinstalling the system or Nx Witness Server may erase settings and data. Back up important files beforehand.

Prerequisites

· Ubuntu Desktop installation image
You can download it from the official Canonical Ubuntu website: Download Ubuntu Desktop | Ubuntu. Alternatively, you may use mirror sites closer to your location. Using the LTS (Long-Term Support) version is recommended.

· USB flash drive
Preferably at least 8GB in size and supporting USB 3.0.

· Installation media creation tool
Tools such as Rufus, balenaEtcher, or UltraISO will work.

· Nx Witness for Ubuntu Linux
Download from: Download Nx Witness for Ubuntu Linux.
Please ensure you download the server installer, not the client. The OpenVision Server is designed to merely run as server. Running the client on the same server would potentially cause performance problems.

o Press the Delete key during POST to enter BIOS Setup. 

o Navigate to the Boot tab.

4. Configure network
Set up Internet connectivity in Ubuntu Settings. This is required for the Nx Witness server installation.

5. Install Nx Witness Server
Copy the Nx Witness server installation package to the server, then run the following commands in Terminal:

 

sudo su #password is required after this command

apt update

dpkg -i #drag the Nx Witness server .deb package into the Terminal window

sudo apt-get -f install

#It’s normal if you are prompted about missing dependencies; the last command resolves them.
