Auto upgrade or update your software, other program.

I got question. 1. I have this problem when I use a Ubuntu, also now with my new Kubuntu.
It tell me I have 6 security update are available and also 20 software upgrade are available, to down on bottom of my task bar. (automatic upgrade system) Went I try to upgrade all these program I get a pop up box saying Another application seems to be using the package system at this time. You must close all other package managers, before you will be able to install or remove any packages.
Where do I go or find this to turn it off?, where are they talking about?
It also told me I have to individual upgrade each one on new package, so that mean, I have type each one in manual? Because it won't let you upgrade all them at once?
Also can go to terminal command type in sudo apt-get upgrade, or sudo apt-get update, or sudo apt-get install or install attr. question what attr stand for? which be best way of doing this?
Also I found out if try to use sudo apt-get remove, this is a dirty word, by that meaning it strip off what have put on your computer like if had a kubntu over a ubuntu, it would take of your kubntu leaving with only ubuntu on desktop. it had nothing to do with removing installing or upgrade software. Why do they miss represent what saying... in command in terminal?

This post is not about an improvement to the site, so should not be in the 'Suggestions and Feedback' sub-forum. I will suggest to the mods that it go somewhere else, in order to get the attention that it deserves.

Moved: This thread is more suitable in Linux - Newbie and has been moved accordingly to help your thread/question get the exposure it deserves.
