Hello, everyone, and in this lecture, we are going to cover the Linux Ubuntu installation.
Now, please note that this is completely optional.
You do not need Linux Ubuntu for this course I am, including the installation instruction of Ubuntu,
just so you know how it can be done.
And again, I am I, I highly recommend everyone who's taking my course is to go with S.O.S and S.O.S
operating system.
For those who wants to learn how Ubuntu works or how Ubuntu installation works for them.
I am including this lecture now.
Please, if you do not want to install Ubuntu, simply skip this video entirely and go to the next video.
So getting back onto the Linux Ubuntu first thing first is you have to create a virtual machine for
Ubuntu, where you will install Linux Ubuntu on it.
So for that will go to our Warshel box and I will go ahead and click on you type and the name Linux.
Bunta, by the way, some people call it Kubuntu, some people call it Ubuntu anyway, um, which one
is correct?
Doesn't really matter.
It's just operating system.
You just need to remember some of the features and the configurations or installations that we will
cover when you type in the name automatically the virtual machine.
Or the virtual box will pick its type, which is Linux, because if you type Linux here and Virgin will
pick a bunta, it's all because we type a Bunta in there.
So Oracle was shoeboxes smart enough to define these values for you.
Now, the memory size that is defined is one gig by default.
If your machine has four gig or less memory, then I would recommend that you leave a default, which
is one gig.
I have enough.
So what I'm going to do is I'm going to change it to two gig.
So when you do one zero two, four times two, it becomes two zero four eight.
So that is two gig hard disk.
Create a virtual hard disk.
Leave it at default.
Click create.
And now it's asking you the information, where do you want to save the location of this virtual machine
by default, it's picked the virtual box VM.
You can leave that as is.
But if you wanted to change the location, you could click on this little folder and define the location,
the file sizes coming up as 10 gig.
That's fine.
You can leave that as this hard disk file type is VDI, which is for the virtual box disk image storage
on physical hard disk, a dynamically allocated lead that as default.
If you want to know more information about that, you could definitely click on Guided Mode.
So go ahead and click create.
Now, the the virtual box or the virtual machine, the container has been created.
Now, the next step is that you need to download the operating system software, which is the ISO image
from the Ubuntu Web site for that will go to our browser.
I am using Firefox and I'm going to Google and here I'm going to type Bunde to download and the first
link it's taking me go to download.
And the download of Bunta Desktop, Ubuntu, eighteen point zero four three, maybe you see it a different
version that is perfectly fine and it depends on when you are downloading it at the version changes
over time.
So when you click on and download, it is going to the download page and it will give you thank you
for download a Bunta desktop and it'll pop up this message which would tell you save file and then you
click on OK, it will save it to your default download location.
I have already saved downloaded the Ubuntu ISO image on my one of my folders, so I'm going to go ahead
and cancel because I wanted to save your time.
So for those who have not downloaded, of course you have to click.
OK, so I'll click cancel now.
I downloaded.
I'll go back to my Warshel box and here let me clear the background screen and go back to our other
screen.
OK, looks a lot better now.
Let's go to our virtual machine and click on START.
OK, whenever a virtual machine starts up, it looks for an operating system, so it could be booted
off of that operating system since this is an empty virtual machine, doesn't have any operating system.
It is asking us from where or which source do you want me to start up the operating system?
We need to specify or attach that ISO file that we downloaded for Ubuntu website.
And for that, you go ahead and click on this little folder.
This is going to take me where my file is, so by default, my files are in my personal folder.
If your file is in desktop, go ahead and click on desktop.
But anyway, this is the downloaded image I did earlier, and now I'm going to go ahead and click on
Open.
Now it is attached.
Now go ahead and click start.
You could ignore this top message is just telling you about your mouse.
Let's minimize the Oracle virtual box manager, so we just have this machine open.
All right.
So now what it's doing is.
It actually uploading or bringing the contents of that ice to them, to its memory so it could start
the wizard, the installation, the operating system, installation visit.
So we'll give it a few minutes.
Also, as I'm going through this installation, any time where I know it would take longer, I am going
to fast forward.
So you you probably noticed that from on my side, the installation is going so fast, but it's not.
I am actually fast forwarding the recording.
All right.
So anyway, let's close down this message again.
And now it's coming back and saying welcome to the install page at Try Ubuntu.
You can try Ubuntu without making any changes to your computer directly from this CD.
If you are ready, you can install Ubuntu alongside or instead of your current operating system.
This shouldn't take long.
So we wanted to we don't want to try it.
We wanted to go ahead and click on Install Ubuntu.
OK, so now by default, the keyboard layout is selected for you, U.S., United States and the United
States.
So that's why it's selecting the keyboard and on the right hand side as well.
On the other ones, um, other options available, you could leave that default if you're in the United
States.
Click continue.
All right, what apps would you like to install to start with?
So we wanted to do normal installation and you pick minimalize the nation, which will be basic command
line utilities.
You don't want to go to that.
Just leave it default.
Then other options, download updates while installing a bunta.
So if you do not have Internet while you're installing it, I would not recommend you to pick that option.
Also, even if you do have Internet, I would still keep it out.
And if I need to do the updates, I'll do it later.
So just pick the first option.
Normal installation and click continue.
OK, this computer currently has no detected operating system.
What would you like to do, erase disk and install a bunta?
This will delete all your programs, document photos, music and other files and all operating system.
So this is not going to delete anything that is already in your virtual box or on your computer.
So don't worry about it.
It's basically saying that that 10 gig that we picked out for a bunch to install, it's talking about
that specific 10 gig.
So it's just telling you whatever you have in that 10 gig that you carved out for a bunta, it will
remove or delete all the programs that have anything on that.
So that's perfectly fine.
We know that.
So go ahead and click on Install now.
OK, if you continue the changes listed below will be written to the disk, otherwise you will be able
to make further changes mentally.
Partition table of the following device are changed to this.
The following partitions are going to be formatted to the partition.
No, this.
So that is fine.
These are default setting and it's building your file system on extension four, which is the file system
for Linux.
Go ahead and click.
Continue.
The time where are you?
I am in default and automatically EPICA in New York because I am in New York.
If you are somewhere else and you have Internet connectivity, it will automatically detect your location
and it will pick it and it will show up right here.
So all you have to do pretty much click on continue, but for somehow if it's not, you could actually
move this around or drag it around to get the right location.
Go ahead and click.
Continue.
Username your name, which I'm going to put in my name, Emran Absol, and as I'm typing your computer
name, it's by default is picking based on my first name.
I wanted to change that to something different.
So I'll use a Linux Ubuntu as my host name.
All right.
So in terms of user name, I would like to keep it consistent across.
I usually pick I have Afsal and I'm going to pick a password.
The past restraint is fair.
That is fine, you have two option to automatically log in or require my password to log in.
So we'll leave a default, require my password to log in and go ahead and click continue.
OK, so now it's going to copy the files that is required for this operating system installation, this
could take anywhere from 10 minutes to 30 minutes, depending on the speed of your computer.
So I am going to fast forward from this point on.
And when it's finished, when I get the get the option to reboot, that's when I come back and we will
do the reboot.
See you on the other side.
All right, installation is completed, great news, so as message says, installation is complete,
you need to restart the computer in order to use the new installation.
So go ahead and click on Restart now.
OK, the system is back online now, and I have to login screen, I could go ahead and click on my username
and put in password.
If you wanted to log in as root, you you have to click on not listed, put in the username as root
and the next screen put it a password, log you in as root.
But I wanted to log in as myself so I'll click on my user name and I will go ahead and put in the password.
OK, what's new in a bunta, so this is going to tell you what works differently from all the versions,
you could explore that one by one, but since I already know the changes, I'm going could just go ahead
and click on next live patch.
Now, like Patch requires you to do a patch which needs you, which in which your machine needs to go
out on the Internet.
You could click on it.
But before you do that, please make sure your machine has bridge, network, adapter, meaning if you
go to your virtual box and go to the setting.
In the setting, go down to network, and right now you notice it is it stays attached and that you
would have to select a bridge adapter.
Click OK.
And now it should be able to assign an IP to that machine and then you could do live setup or whatever
that you want to do or even updates.
So, anyway, for this purpose, for this purpose, go ahead to just simply skip and click on next.
You are ready to go.
You can use software to install apps like these, so if you wanted to use the software, these third
party software, you could go to your software options and download these programs.
Anyway, go ahead and click.
Done.
OK, so now you have a Bunta desktop, you could definitely go into each one of these categories and
these different differential application programs and go through it to actually familiarize yourself
with Ubuntu desktop.
But, uh, Linux is pretty much on the command line environment.
So I would say that you should open up your command line terminal and run the commands.
Also, if you have not updated your software and there is a newer software that is out there on the
Bunta website that is available, it will actually pop up this message which says updated software has
been issued.
So do you want to install it again?
If you want to install it, make sure your computer.
This machine has Internet access.
And on the network side, on the virtual box your network has not nattered, but whorish adapter.
If you do everything you have confirmed, then you do install it now.
But anyway, again, this is LEPs testing.
I don't want to update any software.
I'll just say remind me later.
Now, if you wanted to open up the terminal, you could just simply.
Right.
Click on your desktop and click on Open Terminal.
And there you have the same terminal that you will get in any Linux operating system, primarily like
S.O.S or RedHat.
This is the same terminal you can run commands like of minus eight.
You can run commands like S minus L and all bunch of commands.
Anyway, again, Ubuntu is Linux operating system.
I would say 80 to 85 percent of the commands that we use it in S.O.S and Readhead are also applicable
in Ubuntu as well.
So try it out, run different commands.
And again, this is just for experiment purposes for for your awareness, how the installation works.
You could have them installed and see how it looks.
Good luck.
I'll see you in the next lecture by.
