How to update and upgrade Zorin OS

These are the first command lines I've learned as a fresh Linux user. In fact, these are the first command lines I wrote in the Terminal immediately after installing Zorin OS on my netbook. And this is what I do every day to keep my system up to date, stable and secure.

I open the Terminal by pressing in the same time the keys:

Ctrl+Alt+T

And the Terminal looks like this:

Update Zorin OS via command line

First, I do the update. In order to do this, just after the blinking cursor line, I type:

sudo apt-get update

and then I hit "Enter" key.

Immediately, I'm asked for the administrative password. (In Linux, nothing is allowed to move without written permission!).

I type the password (remains invisible) and then I press "Enter" key. And a bunch of lines start flowing on the screen, just like in the screnshot bellow:

Fig.3 - Let the Matrix flow... :)

And, when is done, it looks like this:

And then...

Upgrade Zorin OS via command line

I type the line:

sudo apt-get upgrade

And press "Enter" key.
Usually, this time it doens't ask me for pasword. Only if I wait for more than 5 minutes between the two operations. But... looks like this time I did expected too long!

 And that's it! Now, I can close the Terminal...

I'll update this post.

More about upgrade

Sometimes, - not always -  during the process, I'm informed about certain upgrades available and I'm asked if I accept it or not. Like in the example bellow.

Fig.7 - Upgrading...

Of course, I accept it. In order to do that, I press "y" key and then "Enter" key.

The lines start flowing again till the familiar end...

And, during the whole process another widows appears. It is the Update Manager, an app that is also used for keeping the OS up-to-date. When it does...

I click on "Install updates" button.

 Then, of course, I click "Close".

These are the steps I take daily.

Maybe some experienced Linux users (especially the Ubuntu fans) would say that if I use the command lines is no need to use Update Manager. While the new Linux users perhaps would feel happier if I would say them just to use easier method : Update Manager. They would thus have a motive get read of the "ugly" Terminal.

The fact is that, maybe I'm overly careful doing both ways, BUT definitely, Terminal must be used for keeping Zorin OS up-to-date. Maybe other things can be done in the good old (graphical) way  we are used to do as Windows users, but, there are still some things that Linux imply the command line.

Anyway, for me, this was a good reason to get accustomed with the Terminal... And now I really like it! :-)
