Run Dmg File In Ubuntu

  • See also: How to work with DMG files in Linux. On Ubuntu, you’d do it like this: sudo apt-get install dmg2img Once you have dmg2img installed, begin converting the DMG file: dmg2img file.dmg After a few minutes, you should have a second file called image.img. This file can be used like an ISO.
  • A.dmg file is kind of like an USB stick in a file and can be handled more or less the same way. To install from a.dmg file you usually do the following: double click the.dmg to make its content available (name will show up in the Finder sidebar), usually a window opens showing the content as well.

Ubuntu Server › Whether you want to configure a simple file server or build a fifty thousand-node cloud, you can rely on Ubuntu Server and its five years of guaranteed free upgrades.

Note: Ubuntu is primarily distributed over the Internet as CD/DVD image files, called ISOs. If you have downloaded an ISO image, please refer instead to ../FromUSBStick (to install an ISO image on a USB flash drive) or BurningIsoHowto (to burn an ISO image onto a CD-ROM).

The Ubuntu 9.04 netbook remix and some specialized machine images are distributed as disk image files, called IMGs. A typical example is operating systems for Raspberry Pi. This page describes how to install from a .IMG file.

You need to write the downloaded IMG image to a device that your computer can boot from. For netbooks this is usually a flash memory device, such as a USB flash drive or SD memory card. You can also write the IMG file to an external USB hard drive, although these instructions use the term 'flash media'. The device must have sufficient capacity for the install (1 GB or larger is recommended), and you may need a USB adapter or SD card reader on your computer in order to write to it.

Warning: This will destroy all data on the destination device. Please backup all data to other media before proceeding.

Be sure to verify that your computer supports booting from the device you have selected for installation. Many computers can boot from a USB drive, and some from other sources. Check the documentation on your specific model of computer for the procedure to boot from the selected device.

The GettingUbuntu page has links to the IMG and ISO image files, as well as other methods of GettingUbuntu.

MD5 Sums

Before writing your flash, it is highly recommended that you verify the md5 sum (hash) of the .img file. For instructions, please see HowToMD5SUM. For the current list of Official Ubuntu MD5 hashes, see the MD5SUMS file for the release you're using under http://releases.ubuntu.com (and optionally the PGP signatures in the MD5SUMS.gpg file), or see UbuntuHashes. This ensures that the file was not damaged during the download process and is 100% intact.

Graphical Interface

Links that describe the Win32 Disk Imager with more details:

Win32DiskImager

Win32DiskImager/compressed-image 2 USB-or-SD

  1. Visit the Ubuntu download site (for example, http://www.ubuntu.com/download/desktop ) and download the *.ISO file corresponding to the version of Ubuntu that you want (you probably want Ubuntu 12.04 for 64-bit PCs)

  2. Download Disk Imager from https://sourceforge.net/projects/win32diskimager/files/Archive/Win32DiskImager-0.9.5-install.exe/download and install the program. It will create a start menu entry under Image Writer, called 'Win32DiskImager'. You should see a window like the screen shot above.

  3. Insert your flash media
  4. Note the drive letter assigned to your flash media
  5. Start Disk Imager. It will autodetect USB devices.
  6. Select the downloaded file and target device, and click 'Write'
  7. Remove your flash media when the operation is complete

Command Line Interface

  1. Download the desired .img file

  2. Download flashnul from http://shounen.ru/soft/flashnul/index.html#download

  3. Attach your USB drive

  4. Run flashnul -p

  5. Note the physical device number for the USB drive

  6. Run flashnul <number obtained in prior step> -L pathtodownloaded.img

  7. Answer 'yes' if the selected destination device is correct
  8. Remove your USB drive when the command completes

Graphical Interface (up to 12.10, for later versions use mkusb or the commandline method below)

  1. Download the desired .img file
  2. Install the usb-imagewriter package

    • If your release does not include this, download it from Oliver's PPA

    • If imagewriter fails to launch, you may need to install python glade2 support. Install the python-glade2 package or Run sudo apt-get install python-glade2

    • If your release does not include it and you are running 9.04 Jaunty Jackalope then run this command from the console:

      • sudo apt-get install usb-imagewriter

  3. Open Applications -> Accessories -> Image Writer

    • KDE users will find this in Applications -> Utilities -> Image Writer

    • from the command line, from the console:

      • sudo imagewriter

    • on some usb-imagewriter versions (console command: imagewriter) the application fails to write if the image path contains blank spaces, exiting with 'IndexError: list index out of range'.

  4. Insert your flash media
  5. Select the downloaded file and flash device, and click 'Write to Device'
  6. Remove your device when the operation is complete

mkusb

  • Download the desired .img file
  • Install mkusb from the PPA with the following command lines
    • If you run standard Ubuntu, you need an extra instruction to get the repository Universe. (Kubuntu, Lubuntu ... Xubuntu have the repository Universe activated automatically.)
  • Follow the instructions in the quick start manual.

    • View or download the quick start manual http://phillw.net/isos/linux-tools/mkusb/mkUSB-quick-start-manual.pdf

    • Alternate link to the quick start manual version 11../../mkusb/mkUSB-quick-start-manual-11.pdf

    • Alternate link to the quick start manual version 12 alias dus../../mkusb/mkUSB-quick-start-manual-12.pdf

  • Read more about mkusb at this link: https://help.ubuntu.com/community/mkusb

Command Line Interface

Be very careful about which /dev device you write to. If your machine is booted up off of disk /dev/sda, and your usb stick is on /dev/sdc, and you accidentally write to /dev/sda instead of /dev/sdc, your filesystem will be irreparably damaged and you will lose all of your files.

  1. Download the desired .img file
  2. Open a terminal and insert your flash media

  3. Look at the output of sudo dmesg | tail -20 to determine the device node assigned to your flash media (ignore the device number; e.g. /dev/sdc, not sdc1)

    • Example output of dmesg, where the device node is 'sdc':

    • [ 5046.396364] usb-storage: device scan complete

    • [ 5046.397075] scsi 10:0:0:0: Direct-Access USB Flash Memory 1.00 PQ: 0 ANSI: 0 CCS

    • [ 5047.068761] sd 10:0:0:0: [sdc] Mode Sense: 23 00 00 00

    • [ 5047.068769] sd 10:0:0:0: [sdc] Assuming drive cache: write through

    • [ 5047.075021] sdc: sdc1

    • [ 5047.076459] sd 10:0:0:0: [sdc] Attached SCSI removable disk

  4. Run sudo umount /dev/devicenode

  5. Run sudo dd if=/path/to/downloaded.img of=/dev/devicenode bs=1M

  6. Remove your flash media when the command completes (you may need to wait a few extra seconds for it to finish)

Command Line Interface

  1. Download the desired .img file
  2. Open a Terminal (in /Applications/Utilities/)

  3. Run diskutil list to get the current list of devices

  4. Insert your flash media

  5. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)

  6. Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)

  7. Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskNbs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img, /dev/rdiskN is faster than /dev/diskN). If you see the error dd: Invalid number `1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.

  8. Run diskutil eject /dev/diskN and remove your flash media when the command completes

Don't junk your old Mac hardware just because it can no longer get new software updates. Get some new life in your old Macs with the GNU/Linux operating system! We'll show you how to 'try it before you buy it' so to speak to see how a specific version of GNU/Linux, Ubuntu, will run on your aging Mac.

Why bother trying GNU/Linux on your Mac?

I have a late 2010 MacBook Air. It's not as fast or as optically pretty as my 5K iMac nor my iPad Pro for that matter. I do, however, use it daily. I'm writing this article on it. As old as it is, it's 'good enough' for what I use it for and I still prefer the keyboard on it to the one on more modern MacBooks.

Windows

My MacBook Air just made the cutoff for being compatible with the newly released macOS High Sierra. I'm happy to know that for at least one more year, I'll be able to get the latest and greatest doodads, bells and whistles, and more importantly, I'll get the latest security updates (good thing too as while I'll write this, we've just found out that WPA2 has been cracked and clients will need to be updated with security patches).

However, Apple at one point will deem this well working, useful, good-enough MacBook Air as unworthy of any more updates. And as I understand the reasons why my venerable MacBook Air can't be supported indefinitely, I still find it to be wasteful that a decent-enough, capable, and not to mention still functioning computer be put to pasture because of lack of software updates.

This is where GNU/Linux comes in. GNU/Linux is a free and open source operating system very similar in many respects to the under-pinnings of macOS. It comes with modern networking capabilities, web browsers, and content creation tools. Not only is it known to run well with older hardware, but you will also get many years of software and security updates that you'd likely miss out on if you were to remain on a macOS-only installation.

See how well Ubuntu Linux runs on your Mac

You needn't throw out the baby with the bathwater and wipe your old Mac's hard drive clean before trying it out. All you need is a USB drive of a least 2GB in size and an internet connection to get started. Here's how to do it.

Get your USB drive ready

Ubuntu
  1. Backup your Mac.
  2. Launch Disk Utility.
  3. Attach your USB key to your Mac.

  4. Select your External USB device from the list of volumes. (BE VERY CERTAIN YOU SELECT THE PROPER DEVICE).

  5. Click Erase to format your USB key.
  6. Name your USB key.
  7. Select MS-DOS (FAT) as the type of Format you wish to perform.

  8. Click Erase.

Download the Ubuntu Linux installation file.

  1. Go to the Ubuntu website.
  2. Click Ubuntu Desktop.
  3. Select the Ubuntu Linux version your prefer. If you want longterm support and stability, select Ubuntu LTS (recommended). If you prefer the latest software bells and whistles, select the non LTS Ubuntu.
  4. Download the file.

Prepare your USB key to run Ubuntu Linux

We now need to make the USB drive capable of booting Ubuntu Linux with special software. Ubuntu recommends using Etcher.

  1. Go to the Etcher website.
  2. Download Etcher for macOS.
  3. Install Etcher by double clicking the .dmg file you downloaded.
  4. Launch Etcher.
  5. Select the ubuntu install file known as an Image.
  6. Choose the USB drive you prepared with Select Drive.

  7. Click Flash to start the process.

Try Ubuntu Linux!

You're now ready to try Ubuntu linux by booting off of your newly created bootable USB key drive.

  1. Leave your USB Key installed into a USB port on your Mac.
  2. Click on the Apple Icon at the top left of your menu bar.
  3. Select Restart.
  4. When you hear the familiar 'Bing' sound press and hold the alt/option key.
  5. You'll see the 'Startup Manager' and you can now select to boot from the EFI Boot disk.
  6. Select Try Ubuntu Without Installing.
  7. Tap Enter.

  8. Ubuntu Linux will now boot up!

You'll be able to connect to Wi-Fi, browse the web, write up an article (or anything else you may want to do) without making any permanent changes to your existing hard drive. See how much you like it and you can eventually install Ubuntu side by side with your macOS install or go full bore with a Linux only installation (tutorials coming later).

What do you do with your old hardware?

I get a real kick out of repurposing old technology with new abilities. I really value the longevity of a computer system that can still run modern software. If I can keep it going beyond it's expected lifespan, I'm a happy camper. What's your take? What do you do with your old hardware? Let us know in the comments!
