How can i permanently stop/disable/kill this, using command line?

(every-time it pop-ups like i am showing my own presentation, or i left my PC for idle longer and came back to give my lecture, this Popup shows, which is very very annoying in many use case i had).

On that Update Manager dialogue, click "Settings".

Then, next to the option "Automatically check for updates", use the drop-down list to select "Never". " You can still get updates by opening Update Manager yourself and clicking "Check", or by using sudo apt-get update; sudo apt-get upgrade, but it won't pop up by itsself any more.

From the command line you need to edit the file /etc/apt/apt.conf.d/10periodic

I believe changing all those options to "0" will result in the behaviour you expect.
