Unit 6: Lesson 4 Lab 4.51

Purpose

In this lab, you are given the task of using a virtual system to install an operating system. The objective is to successfully install the virtual software to then install Lubutnu, a version of Linux, an open-source operating system, and evaluate differences from what you have experienced with Windows or MacOS.

What is Lubuntu?

Lubuntu is an official Ubuntu flavor which uses the Lightweight Qt Desktop Environment (LXQt). The project’s goal is to provide a lightweight, yet functional Linux distribution based on a rock-solid Ubuntu base. Lubuntu provides a simple but modern and powerful graphical user interface and comes with a wide variety of applications so you can browse, email, chat, play, and be productive.

Lab Instructions

Follow the lab instructions for installing both Oracle VirtualBox and Lubuntu.

On uCertify, in section 4.5 for the Lab, see the four exercises at the end of the Lubuntu setup instructions. Complete the exercises and provide your written responses.

Most people are familiar with Microsoft Windows because it’s so popular. Not everyone is as familiar with Linux, though. In this lab, you are going to install Lubuntu on your machine. The goal is to familiarize yourself with another OS and to understand that other operating systems aren’t scary or mysterious. They all do similar things; it’s just a matter of figuring out how.

Normally, installing a second OS involves a relatively complicated process where you need to dual boot your computer. We’re not going to do that here. You will use a technology called VirtualBox, which allows you to create a new virtual system on your hard drive and not affect your existing Windows installation. I promise you that this lab will not mess up Windows on your computer! And when you’re finished, you can just uninstall VirtualBox, if you want, and nothing will have changed on your system.

The first two steps are for preparation. You need to download Oracle VirtualBox and a version of Lubuntu. Really, any version of Lubuntu is fine, but I’ll point you to a 32-bit version of Lubuntu, which should minimize any compatibility issues. Depending on your network speed, the download could take an hour or more.

1. Download Oracle VirtualBox.

Select VirtualBox For Windows Hosts, unless, of course, you have a Mac, and then you need the one for macOS hosts. Save it to your Desktop or Downloads folder for ease of access.

2. Download to your Desktop or Downloads folder here: https://lubuntu.me/, which will take you to the most updated link for Windows 64-bit:

Unit 6: Lesson 4 Lab 4.53

3. This will give you an older version and the version for Mac: Lubuntu.

There are links on the right side for Lubuntu CD. Choose the one that corresponds to your OS: 32-bit, 64-bit, or Mac (PowerPC). It will download a zipped file with an iso extension. You will need that .iso file later; it will essentially act as a bootable CD for your OS installation.

● Now you begin the installation of VirtualBox.

4. Double-click the VirtualBox icon. If you get a security warning, click the Run button. Then click Next on the Setup Wizard screen.

5. On the “Custom Setup” screen, click Next and then Next again. It will give you a warning about your network interfaces. Click Yes. (Your network connections will come back automatically.)

6. Click Install. This may take several minutes. (You might also need to clear another security warning box.)

7. Once the install is complete, click Finish.

● It’s time to configure VirtualBox.

8. You might get a VirtualBox warning telling you that an image file is not currently accessible. That’s fine. Click “Ignore”. You should see a screen similar to the one shown in Figure 4.49.

9. Click the blue “New” icon to create a new virtual machine. Give it a name (preferably Lubuntu for this lesson). The Type and Version boxes aren’t critical; they don’t affect anything. If you type in Lubuntu for a name, it will automatically set Type to Linux and Version to Ubuntu. Click Next.

10. In the “Memory Size” window, click Next.

10. In the “Hard Drive” window, the default option is “Create A virtual hard disk now”. Leave that option selected and click Create.

11. It will ask you what hard drive file type you want to create. Leave it on “VDI (VirtualBox Disk Image)” and click Next.

12. On the next screen, either “Dynamically Allocated” or “Fixed Size” is fine. If you are low on disk space, go with “Fixed Size”. Click Next.

13.In the “File Location and Size” window, it’s probably best to leave it at the default size of 10 GB. Definitely don’t make it smaller. Click Create. Now you will see a screen like the one shown in Figure 4.50.

● Great! You now have a virtual machine on your hard drive. Now you just need to add something, more specifically an OS, on it.

14. Click the “Settings” button.

15. In the “Lubuntu – Settings” window, click the “Storage” icon.

16.Under one of your controllers, you should see something that looks like a disc icon that says “Empty”. It should look like Figure 4.51.

17. On the very right side of the window, you will have another disc icon with a little down arrow on it. Click that, and a menu will pop up. Select “Choose A Virtual CD/DVD Disk File”.

18. In the window that pops up, navigate to the directory where you stored the “Lubuntu.iso” file that you downloaded. Highlight the file, and then click Open.

a. If the file is not listed, click “Add” at the top of the “Lubuntu-Optical Disk Selector”

b. A file window will open, navigate to where the Lubuntu.iso file was downloaded to

c. Highlight it and click Open

d. Highlight it again in the “Lubuntu-Optical Disk Selector” and click “Choose”

Unit 6: Lesson 4 Lab 4.57

19. Back on the “Lubuntu – Settings” dialog, your drive that was empty should now say “Lubuntu…”. Click OK.

20. Now you are back to the “Oracle VirtualBox Manager” screen. With Lubuntu on the left highlighted, press the green Start arrow (see Figure 4.50). This will begin the installation of Lubuntu.

21. Choose a language, and then on the next screen choose “Install Lubuntu” and press Enter.

22. Follow the Lubuntu installation process.

Unit 6: Lesson 4 Lab 4.58

23. You will get to a screen similar to the one shown in Figure 4.52, which asks you for an “Installation Type”. It looks scary but choose the “Erase Disk and Install Lubuntu” option. This will install it on the virtual disk that you created earlier with VirtualBox, and it will not wipe out your entire hard drive.

24. Continue with the installation process. When in doubt, choose the default and move to the next step.

25.When the installation is complete, click the “Restart Now” button.

Now that the installation is complete, play around in your new operating system! I strongly encourage you to go back through this lesson and complete Exercises 4.1 and 4.6–4.8, but this time in Lubuntu. Windows based exercises are found within the Lesson 4 reading. Remember you want to now complete the same exercises in Lubuntu, documenting how you accomplished the tasks.
