The first thing to do after installing a Linux distribution is to update all installed applications
to their latest version when installed Ubuntu, you've created a username with a password.
This is the user and the password used to login.
Many, if not all administrative tasks, including updating or installing new software, must be started
as good.
What is the clinic's administrator and will have a lot of talks about it in the next lectures to Ron
Cummings is Ruth, which means with administrative rights, use the document into the comment you want
to run is what?
Let's see how this works.
I want to run some administrative comments that fully update all installed applications.
I'm clicking this Ubuntu menu show applications and searching for a terminal, and I'm opening it.
Another quick way to open a terminal is to click on the desktop with the right policies button, then
select and click open in terminal and a new terminal window is opening.
So in the terminal, right, so the Apte update.
It's asking for my password and the comment will run with road privileges.
Not that it requires an active Internet connection.
When it's done, I'll run a second command, which will actually update all applications to their latest
version.
So the Apte full Myners upgrade.
It's prompting the user to enter WiFi to continue or end to stop, note that this comment requires a
good Internet connection since it's downloading a lot of software.
It's the conclusion if you prefaced a comment with pseudo, you are prompted for your own past and the
comment will run with road privileges if you are a complete beginner, don't focus too much on this.
Just update the system, because we really dive deeper into this in the lectures to follow.
We are waiting for it to finish.
I'll post the recording until it's done.
And it's done.
The system was fully updated.
The second thing to do is to install the guest additions in the house to PVM.
So in addition to.
They consists of device drivers and system applications that optimize the guest operating system for
better performance and usability, the most important features are better mouse integration, shared
folders and clipboard between the host and the guest operating systems, better with the support and
so on.
Go to devices in the virtual box top menu and click on insert guest additions to the image services
provided as a single image file that is called the box guest additions that Ezo and is located in the
installation directory of Virtual Box.
So it comes with the virtual box and it's already available.
A new window pops up and you can actually run.
He's asking for your passport because it Oleron is the super user, which is good.
And installing the guest additions is adding some additional modules and so on.
And it's done if there's any errors or you don't want it to run automatically, you can run it manually.
In a terminal move to the directory where the guest additions is no file was mounted using the city
comment said a wide space for media, my username student.
And I'm pressing the turkey for greater completion and I'm hitting enter this is the directory where
the guest additions file was mounted.
Let's see the contents of this directory by running the comment.
Here we see some executable files for different operating systems, including Linux, Windows and Mac.
We are running Linux, so we are going to run the Linux script, which is a V box.
Linux additions that run is what I'm executing the script.
Sudar Besch.
And the name of the script, you can use tab for auto completion.
This is one way of executing scripts in Linux and running.
He's doing the same thing as before.
After it finished, it's recommended to restart the PVM in order to load the new kernel modules so you
could simply execute the reboot comment.
At this moment I'm restarting the VM.
After the system restarts, you will be able to criticize the virtual box window and the to to screen
resolution will be updated accordingly.
Now it looks better.
I can exact the little box additions also note that each version of a virtual box, even minor, releases
sheep with their own version of the guest additions while it's kept stable so that guest additions already
installed in a vault should continue to work when the actual box is upgraded on the host for best results,
it is recommended to keep the guest additions at the same version.
So I repeat the process of installing the guest additions after operating Will Shellbacks.
And the last thing I'd recommend you to do is create a snapshot of the current state of the Veum.
This is a very powerful feature because the snapshots allow you to save a particular state of a VM.
This can be useful when you want to test something or we are about to make a change to the VM and you
need to be able to go back to a working instance if something breaks.
This is our case will run lots of Cumming's install and update software, create and delete files and
many more.
As we are learning by doing, there's the chance that something will break the system instead of installing
it from scratch, will only roll it back to this working state.
This is a serious timesaver.
So to create a snapshot of a running VM, go to the main menu of a virtual box click machine and take
snapshot.
He is a good idea to fill out the name and the description because you might take multiple snapshots
and you don't want to get confused when restoring only a specific one.
It has created the snapshot.
To see the snapshots in the virtual box manager, click this icon and then snapshots.
You'll be presented with the taken snapshots, say you are working in your pvm and you make a change
that breaks the system, Watada required the steps to roll it back to one of the previous snapshots.
First, the VM must not be running.
You can restore a snapshot only if the VM is either in a safe state or it's part of.
So I'm parking off the machine.
I'm selecting the Veum from the left pane of virtual box manager and clicking on snapshots.
I'm selecting the snapshot, I want to start and then click restart.
In this window, I can create a new snapshot of the current machine state or not, this is supposably
the broken state.
So I am not selecting this option.
I'm restoring it.
It was restored, so I can start it.
I advise you to play around with snapshots is, in my opinion, this is a must use feature when working
with virtual machines.
