- In this video, I will show you how to install Ubuntu LTS.
But first let's talk about this LTS thing a little bit.
So the thing with Ubuntu is that there is a new release
every six months, typically in April and in October.
That's a 04 and a 10 release.
And these new releases are maintained for nine months only.
That doesn't really work
if you want to use it in production, and that is why Ubuntu
is making the Long Term Support releases.
And that is what we are going to install, Ubuntu LTS 22.04.
It was released in April 2022.
And the next Ubuntu LTS release will be available
in April 2024, '26, and so on.
And the nice thing about Ubuntu LTS
is that you have multiple years of support on it.
Now when you go to the ubuntu.com website,
you will find different Ubuntu versions.
Where you should be looking at is the desktop version.
The server is very convenient for on a server,
but it doesn't have a graphical user interface by default.
So I wanna make it as easy as possible
and work with the desktop version.
Install that in a virtual machine or on hardware,
but you better do it in a virtual machine
because that is giving you some flexibility
to increase or decrease disk sizes later on.
Then make sure that at least you have one gigabyte of RAM.
At least you have 10 gigabytes of disk space.
And a second disk will be added later in class.
So make sure that you have a virtual machine
that meets these requirements,
and then you can start the installation,
which is what I will show you now.
All right, so if you are going to install Ubuntu,
this is what you will first see.
This is the boot loader.
Just hit Enter to accept the default.
And after doing so, you will see
that the Ubuntu installation system is loading.
That might take a minute.
So a little bit of your patience, please.
(cheerful music)
So Ubuntu actually makes sound when it is ready to install.
You are going to select English,
and then you need to click Install Ubuntu.
There is an option to run Ubuntu
straight from the installation disk by using Try Ubuntu.
I don't wanna try it.
I want to install it.
So we need to click Install to load the installer.
English United States, English US,
is what we are going to use.
So select those, then you click Continue.
And here you can select what it is that you want to install.
Now honestly, I don't need the normal installation.
I would recommend to go for the minimal installation,
because we are not going to use office software
or games or media players.
A minimal installation is just a little bit faster.
Now in case you are installing Ubuntu directly on hardware,
you might want to use the option
to install third-party software
for graphics and Wi-Fi hardware.
The thing is that you get proprietary drivers
when it is needed, and that is mostly better performance,
but in Linux, it's not always seen very well
that some of these drivers are proprietary.
So do whatever you want.
There is no harm in selecting this option.
So just select and then click Continue
to continue your installation.
So here you can see that already the screen is changing.
That is because at this moment,
the appropriate drivers have been loaded.
Next it is asking what you want to do.
Well, what you wanna do is Erase disk and install Ubuntu.
That will remove everything that is on disk.
And Something else,
you really don't want to do Something else.
Something else means a multi-boot system.
Don't use multi-boot, just install Ubuntu
in a virtual machine.
That's so much more convenient, and there is no disk
for the original data on your hard disk.
So make your choice, and then you click Install Now
to start the installation.
Here it's prompting to show you what it is going to do.
So it's going to tell you that it will overwrite your disk,
and is that okay?
Yeah, that is okay.
So I am clicking Continue,
and that'll start the installation procedure.
So you need to select where you are.
Based on your selection, it will choose the local settings,
and the local settings are about language and time format.
And if you are okay, then you click Continue.
And then it's asking, "Who are you?"
So I need to enter my name.
And I'm using student.
Feel free to use your own name if you want to.
And I need to enter a password as well.
It's complaining that my password is weak.
I know it's weak.
I don't care about it too much.
Do not select Log in automatically,
because Log in automatically means
that your Linux installation is not protected at all
by any password or whatsoever.
So make sure you have Require my password to log in,
and then you click Continue.
It's nice to see
that you can also get your authentication credentials
from Active Directory,
if you have an Active Directory available, but I don't.
So I'm just clicking Continue
to start the Ubuntu installation.
And this'll take a little bit of time.
Count about 10 minutes.
So a little bit of your patience, please.
All right, the installation is now done, so we can Restart.
And then after the restart, we need to do some final things
to set up the user environment.
Do mind that you need to press Enter
in order to make the restart.
And there we go, the messages that you can see on the screen
right now are quite normal.
These are messages generated by the Linux kernel.
And now it's booting again.
And that'll take a minute, and then you'll be able
to select your user account, start working.
As you can see, the same graphical interface is used
as on the CentOS system.
That's because both systems are based on the GNOME system,
or G-NOME system, as some people say,
which is the main graphical interface.
Even if these distributions look a little bit different,
there are so many things that are similar
between the distributions nowadays,
including the GNOME interface.
So I'm logging in with the user account that I just created.
And then it is launching the first-time wizard.
I would suggest you skip everything
because this is not important at all.
And we don't care about the graphical applications.
What we care about is the terminal.
Let me do the final things that I need to do
before getting started.
And in order to do so, I'm clicking in the upper-left corner
on Activities.
Then the search bar arrives,
and the search bar is really the convenient thing
that you wanna be working with.
I type power, and I don't wanna power off,
but I want to go to the Power Settings.
And in the Power Settings, I'm making sure
that Screen Blank is not going to happen after 5 minutes,
but it will Never happen.
Then the second thing that I would like to do,
I'd like to start a terminal.
So there we go.
This is the terminal,
and this is what the Ubuntu terminal looks like by default.
There is one thing only that I want to change.
And in order to change that, I need to go here
to the icon with a couple of lines
in the upper-right corner.
And I need to select the Preferences.
And let me take this away, the prompt for new updates.
And I'm going to click on Unnamed,
where we can see that this is using a Terminal bell.
I don't wanna be using the terminal bell,
because this terminal bell makes noise every time
I'm typing the wrong key, and that's just annoying.
And this is what I'm going to keep,
the aubergine background.
It is nice because that means that throughout this course
it's so easy for you to see when we are on Ubuntu
and when we are on the CentOS system.
So that's all.
