Update to latest Bluecherry Version?

Forgive me if this stated someplace. I did glance at the Install / Documentation and did look over many posts. I assume to update and upgrade to the current Bluecherry software I ssh to the server and from the command line run the commands to patch and update the software?

Something like sudo apt-get update and sudo apt-get upgrade?
In one post I did download the RC4 version, but still on Version: 3.1.0-rc2 and want to get to rc3.
Just want to make sure I am doing the updates the correct way. For me for what I am doing and wanting the rc2 has been working very well and been very stable for me. Glad I switched back to Bluecherry from Blueiris


I have answered my own question, I used Webmin to check system status and updates, And Can use the regular apt-get update & apt-get upgrades and install that way.

On a side note, I had installed Ubuntu without the desktop GUI interface. In place of it I installed Webmin to be my web / GUI management interface for the DVR server. It is a useful tool. If you are running the Ubuntu server without Desktop you might want to look at this application to install and make it easy to manage the Ubuntu and the patching / updating process that way.
