In-Client Upgrade Issue

Following the software upgrade to DW Spectrum® IPVMS v4.0, it has been found that the Client software will successfully update when using the in-client upgrade feature, but the Server software will not complete and will remain on an “Installing…” status message.

This issue has been addressed by the release of superseding versions (v4.1 and up) of the software.  This issue can be resolved by manually upgrading the DW Spectrum IPVMS software version to build v4.0.030434 or newer.

This article will outline how to manually upgrade the DW Spectrum® IPVMS software to version v4.0.0.30434 while using an Ubuntu OS.

**NOTE:  It is recommended to create a Database Backup before making any changes to the hardware or software of a DW Spectrum® Server.  For more information, check out Creating a Database Backup of DW Spectrum IPVMS.

Supported/Affected Devices:

  • DW Blackjack® Server Series (Ubuntu)

Manually Upgrading DW Spectrum IPVMS

To manually install DW Spectrum IPVMS using a Linux Command Terminal:

  1. Download the DW Spectrum® Server installation file (.deb) onto the Server.  If the installation file is placed on a USB stick, connect the USB stick to the Server.
  1. From the Ubuntu Server, open the Command Terminal (CTRL+ALT+T) program and log in to the system as the Super User with the command.

sudo su

When you are prompted to enter the password for the Super User, text that is entered will be coverted and will not display.

Use the password:


**NOTE:  For older DW Blackjack units purchased prior to June 18, 2021, the previously utilized default Linux OS login was “admin/admin”.

  1. Use the Terminal program to direct itself to the file directory where the DW Spectrum® IPVMS installation file (.deb) is located.

It may be easiest to place the installation file (.deb) directly onto the desktop. 

If the file has been placed on the desktop, locate the directory with the command:

cd Desktop

If the file was downloaded directly to the computer’s Downloads folder, the file path would be $HOME/Downloads and the command would be:

cd ~/Downloads

  1. Next, install the software file using the command structure of:

sudo dpkg –i <file_name>

As an example, if the installation file is titled as “dwspectrum-server-”, then the command would be:

sudo dpgk –i dwspectrum-server-

  1. [Optional] After installing the software update, the DW Spectrum® Media Server program will restart.

If you still need to install any missing dependencies, use the command:

sudo apt-get install -f
