  4. Very short bio: Brian Byrne Brian discovered computing around the

    time Intel released the 4004 chip, in 1971. After 1979 he professionally worked across most sectors, education, commercial and finance, in some seriously technical, managerial and hands-on roles. NB: Brian speaks in paragraphs. He founded Linuxing In London (Britain's largest free educational and inclusive Linux group) in 2016, co-organises Covent Garden Pi Jam and the All London Raspberry Pi Jam (mini-science festivals for kids), plus a lot more. He is a freelance IT manager, a thinker and do-er for hire. Want your IT systems organised properly? Pay him, he’ll do it for you! © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 5
  5. Brian’s operating system experience Brian has used, installed, fixed and

    played with over 24 operating systems in 40 years, including but not limited to: TOPS-10, RT-11, RSX, VAX/VMS, CP/M, MS-DOS, AmigaOS, RSTE/E, Classic Mac OS (Lisa), Sinclair_QDOS, Ultrix, OSF/1, SCO Unix, OpenVMS, OS/2, VM/CMS, NetWare 2->3, Windows 1-> Windows 3.1, Windows 95->98 SE, Windows NT 1.0 ->4, Windows 2000, Windows XP, Windows Vista, Windows 7->8.1, Windows 10 and a lot more. Linux was his 15th or 16th operating system! He took it up in 1993 © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 6
  6. Dedicated to Francis Allen © Brian Byrne, 2020 Twitter:@BrianLinuxing Email:

    [email protected] 7 This talk is dedicated to the memory of Frances Elizabeth Allen who died recently. Allen was a maths graduate, who joined IBM in the late 1950s. Initially she taught the new language, FORTRAN. She worked on various supercomputing projects during her career at IBM, even on the notable IBM 7030 and PL/1. She produced major works on optimizing compilers and parallel computing in 1966, 1970 and 1972. Later on she went on to win the Turing Award in 2006. To this day we still use many of her radical ideas.
  7. Objectives 1. Install Linux (from the beginning), use VirtualBox as

    a platform. 2. Learn about virtualising, the Linux installation process. 3. Understand any gotchas. 4. Do the bits that are often left out or not fully explained. 5. The end result should be a Virtual Machine running Linux, which is fully updated/upgraded and ready to use. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 8
  8. Brief agenda 1. A very, very quick installation demo (tick)✅

    2. Discuss the concepts and how we do things 3. Complete a detailed walkthrough with screenshots 4. Recap after each section 5. Explain the key part to running a Linux system for years © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 9
  9. Sections 1. Explaining Linux installations and virtualising 2. The Hypervisor

    and guest operating systems 3. The main Linux installation 4. Post installation tasks 5. Windows issues and fixes 6. macOS issues and fixes 7. Frequently Asked Questions (FAQs) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 10
  10. Broad Categories of Linux installations • Bare metal or as

    virtualised. Then we subdivide down to three general types: • Servers, small board computers or desktop Linux. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 12

    Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 16
  13. Four parts to the virtualising 1. Your hardware (laptop, desktop)

    2. Your hosting operating system (Windows 10, macOS, Linux, etc.) 3. Hypervisor (VirtualBox) 4. The guest operating systems (Peppermint OS 10 (Linux)) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 18
  14. Essential: a working host We are hosting Peppermint Linux within

    VirtualBox, which in turn is hosted under your laptop’s main operating system. So the host operating systems and all of its bits have to work perfectly with VirtualBox, in the first place. See section 8.0 and 9.0 of these slides for troubleshooting help. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 19
  15. Got Windows? Are you running Windows? 1. Is Hyper-V working?

    2. Is virtualisation enabled? Check the UEFI/BIOS, etc? If not, then VirtualBox won’t work and therefore we can’t install Linux. See section 8.0 help with Windows. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 22
  16. Got macOS? Peppermint Linux works under VirtualBox and that uses

    macOS. If you’re running macOS then watch out for application security restrictions in later versions. See section 9.0 of these slides for help with macOS. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 23
  17. Recap: Linux installations and virtualising There are many potential permutation

    of Linux installations, we shall focus on desktop Linux with Peppermint OS 10 (Linux) working under VirtualBox, in turn under your own operating systems (Windows 10, macOS, Linux, etc.) Why virtualise? There is better utilisation of the hardware, it is a little complex but once mastered allows greater flexibility and management of underlying operating systems. NB: The host operating system must be functioning with VirtualBox 6 installed and proper working. This is your responsibility. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 25
  18. What is Oracle's VirtualBox? And why use it? Oracle's VirtualBox

    is a hypervisor which runs across many host operating systems, including but not limited to: Windows, macOS or Linux. In functionality, it provides software-based virtualization, and is freely available. In turn virtual machines can, in theory, be moved between different host operating systems without any major issues. For our purposes it provides a standardized platform and is not host specific (compared to say, Hyper-V, Parallels, etc.), download VirtualBox at https://www.virtualbox.org/wiki/Downloads © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 28
  19. What is Peppermint Linux? And why use it? Peppermint OS

    10 is a derivative of Lubuntu 18.04 LTS and uses the Ubuntu repositories. In terms of design it is slightly simpler and thus faster than standard Ubuntu, but in functional terms it is the equivalent. Any application that can be installed on standard Ubuntu 18.04 works on Peppermint OS 10 Linux, without any change. It has less hardware requirements and is, therefore, a bit faster. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 30
  20. Getting Peppermint OS In this instance we are using Peppermint

    10 Respin (32 bit) ISO. https://github.com/peppermintos/Peppermint-10/releases/download/10_20191210/Peppermint-10-20191210-i386.is o Peppermint OS is available at https://peppermintos.com/guide/downloading/ There is a full installation guide at https://peppermintos.com/guide/ © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 31
  21. A word about LTS and 32 bit LTS - Long

    Term Support Ubuntu type releases come out every six months (April and October), but LTS versions are supported for 5 years, thus are preferable, 16.04, 18.04, etc. Is 64 bit better than 32 bit? Not always, 32 bit Linux can work better with 64-bit host operating systems, if 64 bit doesn’t work for you then use 32 bit. Functionally, for our purposes, there is, little to, no difference between them. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 32
  22. Recap: The Hypervisor and guest operating systems Firstly, we need

    a fully working host operating system (Windows 10, macOS, etc.), virtualisation must be working (see 8.0 and 9.0 for help). The hypervisor allows us to manage assorted virtual machines and in one of those VMs we shall install Linux via the Peppermint OS ISO. Each layer plays its part: • Hardware (Laptop or desktop PC) • Host operating system (Windows or macOS) • Hypervisor (VirtualBox) • Virtual Machine (Peppermint OS 10 - Linux) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 34
  23. Prerequisites or not There are no assumptions on knowledge or

    skill levels. Everything is explained from scratch, but there are certain requirements to be successful here: A laptop enabled for virtualisation (Hyper-V, if Windows) VirtualBox 6 installed and working. Download Peppermint OS 10 Respin (32 bit edition). Ideally 12+ Gb of free disk space. 4Gb or better of RAM. A Mac, Windows 7 (64 bit when possible) or better. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 36
  24. Technically, what we are going to do: 1. Create a

    virtual machine entry under VirtualBox 6. 2. Fix the settings for the virtual machine in VirtualBox 6. 3. Boot Linux (Peppermint OS 10, it’s a similar procedure for other distros). 4. Run the installer. 5. Install Peppermint Linux (from within a “live” copy of Linux). • Take the defaults and click on Continue 6. Shutdown the “live” Linux 7. Post installation VirtualBox tasks: • Check and remove the original boot media. • Update/upgrade from the repositories, if time allows. • Install the Guest Additions © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 37
  25. How are we going to do it? 1. I shall

    walk you through each step and recap each section. 2. Please, do not follow everything robotically, use common sense! 3. The graphics (screenshots will vary slightly depending on if you installed VirtualBox on Linux, macOS or Windows, but they are essentially the same. 4. We will look at a short description of the task, then I will take you through it via screenshots. 5. Remember it is much, much easier than it looks :) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 38

  35. 2.1 A quick explanation: Starting up VirtualBox and creating an

    entry We have started up Oracle’s VirtualBox for the first time, created an initial entry, left it in place, then pointed the virtual machine entry to the ISO image we downloaded earlier. Now we start it. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 57
  36. 3. Boot Linux (Peppermint 10) a. Select <the name of

    your virtual instance) ->Start (click on green button). b. “Try Peppermint OS Live” and hit the return key. c. It will start up in console mode, ignore any minor error messages. d. Wait until you see the “live” Linux desktop. e. Problems? Kernel panics? Running Windows? See below. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 58
  37. 4. Run the installer a. Select “Install Peppermint 10” and

    hit the return key. b. Wait for the Welcome screen. c. Follow the instructions below. Also, see the first part of https://peppermintos.com/guide/7-oem-installation/ © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 63

    updates while…” Just keep doing Continue after you have fully read the screens. There are only six simple steps: a) Welcome b) Keyboard layout c) Updates and other software (take care here) d) Installation type (and write changes) e) Where are you? f) Who are you? It installs Linux, it tells us so and then we shutdown via the Menu. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 67
  41. Break time Typically, installing Peppermint Linux takes anywhere from 20

    to 45 minutes to install, depending on the speed and age of your hardware. Time for a quick cuppa! © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 76

    Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 79
  43. 6.1 Explaining it all and the post installation VirtualBox tasks

    We have distilled the contents of the ISO Linux image into a file structure under VirtualBox that pretends to be a real disk. We have set-up this new Peppermint Linux disk with the defaults you typed in. There are three minor tasks to complete then everything will be ready! 1. We must remove the live boot media. Or when it reboots it might return to the installation media, instead of the newly installed system. 2. Then we should always update the system before installing anything else. 3. Thirdly, install the Guest Additions (permits resizing of the screen, etc.) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 83
  44. Recap: The main Linux installation That was the hardest part,

    the main installation, the rest is comparatively easy. Remember to view the demo at the start of this talk as well. If the demo goes too fast then slow down your video player to follow each step. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 84
  45. 7. Post installation VirtualBox tasks 1. Remove the boot media.

    2. Update from the repos, a word of warning. 3. Add the Oracle Guest Additions, which allow for bigger fonts and screen resizing. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 86
  46. 7.1f Back to the Oracle VM VirtualBox Manager © Brian

    Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 92
  47. 7.2 Update from the repos, a word of warring A

    system update and upgrade must be run before installing any more applications, whenever possible. The first update of Peppermint Linux after a clean installation can take 25-30 minutes depending on the network speed and the capacity of the laptop, etc. It must not be interrupted or will, potentially, ruin the new setup. There are various ways of doing it (via the Update Manager, in the icon tray, with the Synaptic Package Manager or on the CLI). Let’s do the CLI method for the sake of speed. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 93
  48. 7.2.1 Post installation - update/upgrade a) Go to Oracle VM

    Virtual Manager b) Click on the green Start button (wait for the newly created virtual machine to startup fully) c) (Bottom left) Menu-->Terminal-->(wait for the Peppermint Terminal to startup and you should be at a $(dollar) prompt) d) sudo -i e) apt-get update && apt-get -V dist-upgrade (answer y) f) Take any questions with the default <enter> g) When the system upgrade has completed fully and successfully returning to the $ prompt then type, reboot [Remember, don't interrupt apt-get or it might break your Linux system.] © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 94
  49. 7.3 Guest Additions - the quick way 1. Select, boot

    up your Linux virtual machine but wait until it’s fully booted 2. Outside of the virtual machine, look at the top menu: File Machine View Input Devices Help 3. Select Devices-->Insert Guest Additions CD Image 4. Bring up a terminal (see previous slides) 5. Bring up the File Manager (bottom left icons, next to the terminal) 6. Click on the VBox etc entry (under Devices) and it will mount the device 7. Find the virtual CD device with the command, df -h 8. E.g. cd /media/brian/VBox_GAs_6.1.12 9. Check the drive is ok and accessible with the command, ls 10. If that works OK execute the command, sudo ./VBoxLinuxAdditions.run 11. Enter your password. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 96
  50. 12. The process should take about 5-10 minutes during this

    phase. 13. It should return to the $ prompt 14. Now type shutdown -h 1 when everything has completed. 14. Go to the Oracle VM Virtual Manager, press the green Start button 15. Be patient, it does a lot of work now, eventually then you should see the Peppermint OS 10 desktop, and we are done! © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 97
  51. 8.0 Windows issues and fixes Microsoft's Windows has various assorted

    problems with VirtualBox. None of them are insurmountable, but they do take work on your part. Two things that you should ensure are working: 1. Virtualisation 2. Hyper-V Without these VirtualBox may not fully function. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 102
  52. 8.1 Virtualisation Firstly, enable virtualisation in the BIOS. Enter your

    laptop’s BIOS/UEFI setup, then using the manufacturer's instructions change the settings to enable virtualisation. The precise method varies from laptop to laptop, use Google search too! This link works for many ThinkPads but not all laptops, please check your own model’s documentation. https://support.lenovo.com/gb/en/solutions/ht500006 © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 103

  54. 8.2 Hyper-V on Windows The method for fixing Hyper-V on

    Windows varies depending on the version you have installed. Firstly, it needs a 64 bit version of Windows. Hyper-V will not necessarily work on Windows 10 Home, see https://www.zdnet.com/article/windows-10-tip-how-to-enable-hyper-v-and-create-virtual-machines/ The slides below provide basic information on Hyper-V and: • Windows 7 • Windows 8 and 8.1 • Windows 10 © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 105

  63. Q2: Where is the material for this talk kept? These

    slides are on Speaker Deck https://speakerdeck.com/brianlinuxing The video material will be placed on Linuxing In London’s YouTube channel: https://www.youtube.com/channel/UC-qHkg48QRMhhjgKIOuf7qQ © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 118
  64. Q3: What is Ubuntu Linux? And why not use it?

    Ubuntu is a very popular and widely supported version of Linux. It was developed by Canonical and is based on Debian. Given its popularity, if any Windows or similar apps are ever released for Linux then they will probably appear first under Ubuntu. That is why it is important on the Linux desktop. Q4: Why then use Peppermint OS and not straight Ubuntu? Peppermint OS is slightly better for older machines, It is less resource intensive and fully compatible with standard Ubuntu. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 119
  65. Q5: Can I do this installation with other versions of

    Linux? Yes, they are very similar. The overall procedure is comparable. Q6: Why use the 32 bit version here? Isn’t 64 bit better? The 32 bit versions of Linux are more likely to work under your existing 64 bit architecture with VirtualBox. 64 bit is often better, but in this instance the difference is negligible. Later on you can experiment with 64 bit Linux once you have master the theory and procedures relating to Linux and virtualization. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 120
  66. Q7: Does the Linux touch my partition or existing hard

    drive? Where are its disks and my files? No, it runs under VirtualBox which in turn runs under either Windows 7/8/8.1/10 or macOS. Your VirtualBox files are there. They are the big file that you created at the start, everything is in there. Explained here https://www.virtualbox.org/manual/ch10.html See the instructions in section 1a. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 121
  67. Q8: Why do “Try Peppermint 10” and not just start

    the installer directly? Temporarily running the installer under its own version of Linux verifies the setup and shows if the operating system will run in this instance of VirtualBox. We are just being extra careful. Q9: Is that it? Have we finished? Yes, compared to many other operating systems Linux is comparatively trouble free during installation, but if they do occur most errors are minor and can be fixed with time. You will need to do the post-installation tasks and install any additional apps. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 122
  68. Q10: What is the Linux kernel? How can I learn

    more? It is the essence of the operating system, it interacts with the hardware, allowing apps to run and managing memory, among many other things. It is a very, very complex topic best look at the kernel mailing. https://lkml.org/ The Linux Plumbers 2020 conference is on-line and very useful too. https://www.youtube.com/c/LinuxPlumbersConference/videos © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 123
  69. Q11: Linux boots but gives a fuzzy screen Try these:

    1. Install the Guest Additions and try again. See https://www.virtualbox.org/manual/ch04.html 2. If that fails try Lubuntu. 3. If that fails use Lubuntu with the F6 option and toggle nomodeset 4. If that fails try another distro. Q12: I only have a 32 bit version of Windows. Then use the version 5 of VirtualBox https://www.virtualbox.org/wiki/Download_Old_Builds_5_2 © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 124
  70. Q13: Is there any documentation on this? The main Oracle

    documentation page: https://www.virtualbox.org/wiki/Documentation Q14: Why not use just Hyper-V, instead of VirtualBox? Hyper-V runs on only Windows systems, these presentations are cross-platform and focus on freely available software. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 125
  71. Q15: What architectures do Ubuntu and Debian support? See https://www.debian.org/releases/stretch/i386/ch02s01.html.en

    and https://help.ubuntu.com/community/SupportedArchitectures © Brian Byrne, 2020 Twitter: @BrianLinuxing Email: [email protected] 126
  72. Q16: I am using a Chromebook, it is not working

    for me. Chrome OS is *not* Linux, it is close but not really Linux. But have a look at: Set up Linux (Beta) on your Chromebook https://support.google.com/chromebook/answer/9145439?hl=en-GB Chrome OS devices/Crostini https://wiki.archlinux.org/index.php/Chrome_OS_devices/Crostini © Brian Byrne, 2020 Twitter: @BrianLinuxing Email: [email protected] 127
  73. Q17: What do the settings in Storage options mean? See

    the VirtualBox documentation https://www.virtualbox.org/manual/ch03.html Q18: Is there any homework or things we should learn after this talk? Yes, study the Linux command line interface. These free books will help: http://ubuntu-manual.org/downloads and http://www.ubuntupocketguide.com/download_main.html © Brian Byrne, 2020 Twitter: @BrianLinuxing Email: [email protected] 128
  74. Q19: The virtual machine’s screen is really small, what can

    I do? Install the Guest Additions, see section 7.3 and read these links: https://www.virtualbox.org/manual/ch04.html#additions-linux https://linuxize.com/post/how-to-install-virtualbox-guest-additions-in-ubuntu/ https://www.linuxuprising.com/2019/01/manual-virtualbox-guest-additions.html https://helpdeskgeek.com/linux-tips/install-virtualbox-guest-additions-in-ubuntu/ https://help.ubuntu.com/community/VirtualBox/GuestAdditions https://www.tecmint.com/install-virtualbox-guest-additions-in-ubuntu/ © Brian Byrne, 2020 Twitter: @BrianLinuxing Email: [email protected] 129
  75. Q20: Guest Additions doesn’t install correctly, what can I do?

    You might need to install some packages: apt-get update && apt-get install build-essential gcc make perl dkms linux-headers-$(uname -r) © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 130
  76. Q21: What’s the proper system management on Linux 1. Install

    the operating system. 2. Reboot. 3. Do an update/upgrade. 4. Reboot. 5. Add any other apps, as required. 6. Do a weekly update/upgrade (takes 2-8 minutes, typically) 7. Check log files and performance, regularly 8. Only use the root account for a very specific system function, do most work in your own user account, whenever possible. 9. Everything is good to go. © Brian Byrne, 2020 Twitter:@BrianLinuxing Email: [email protected] 131
  77. Q22: How can I learn more about Linux? Are there

    any free courses? This free course and associated links from IBM is an excellent starting place: Learn Linux, 101: A roadmap for LPIC-1, https://developer.ibm.com/technologies/linux/tutorials/l-lpic1-map/ © Brian Byrne, 2020 Twitter: @BrianLinuxing Email: [email protected] 132
