How to Convert an ISO File to a DMG on Ubuntu without Additional Software

=====================================================================================

Sometimes you may need to work with files that are in different formats depending on your operating system. For instance, if you have a Mac computer but only have access to an ISO file created under another platform like Linux or Windows and want it as a dmg (Mac OS X disk image) format instead where possible!

Fortunately enough there exists simple ways how we can achieve this conversion process without any third-party tools - all thanks are due entirely unto powerful Unix utilities available straight from within terminal window of your Ubuntu distribution.

Method 1: Using Built-in Tools

--------------------------

### Step 1: Install the required packages

Before proceeding, ensure that you have the following packages installed on your system. You can do this by running:

```bash

sudo apt-get update && sudo apt-get install dmg2img -y

```

If any of these are not already present, use `apt` to fetch and install them.

### Step 3: Convert ISO to DMG

Once you've downloaded the ISO file onto your system (let's call it `file.iso`) navigate into its parent directory using cd command:

```bash

cd ~/

```

Now run the following commands one after another from within this location:

```sh

# Extract contents of .img file inside a temporary folder called temp_dmg

dmg2img -o ./temp_dmg.file.img

# Convert resulting dmg to iso format while preserving original permissions and timestamps

hdiutil convert -srcfolder ./temp_dmg/ -format UDTL -v output.iso -ooutput.dmg

```

### Step 4: Verify the DMG File

After executing these steps, you should now have a new `.dmg` file named `output.dmg`. To double-check that it has been successfully converted correctly without any issues during transfer or corruption along way, right-click (or Ctrl + click on Mac) on this newly created dmg image and select 'Open with' followed by choosing an appropriate program like Finder which should then open up its contents as expected.

Method 2: Using Third-Party Tools

------------------------------

If you prefer not to mess around with terminal commands or encounter any problems while following the above method, there are also third-party tools available that can help simplify this process for you. One popular option is DMG Converter by iBoysoft which offers a user-friendly interface along side support for multiple input/output formats including ISO -> dmg conversion.

### Step 1: Download and Install DMGConverter

Head over to the official website of DMGConverter 'here'(https://www.dmgconvertdvd.com/), download their software installer (either .dmg or `.exe` depending upon your operating system) and follow through with installation prompts until everything is set up properly.

### Step 2: Convert ISO to DMG Using DMG Converter

Once installed, launch the application by double-clicking on its icon in Applications folder if you're using Mac OS X. Alternatively, search for 'DMGConverter' within Launchpad or Spotlight bar and click on resulting result when found:

In the main interface of DMG Converter, click on 'Add' button located at top left corner and browse for your ISO file. Once added successfully, you will see its name displayed under 'Input File(s)' section as shown below:

Now, go ahead and click on 'Convert' button next to it. The software will now start the conversion process automatically without any further intervention required from your side:

Once the conversion is complete, you will find your newly created `.dmg` file in a designated output location specified by default (for example: `~/Desktop/Output`). Double-click on this to open it up and verify that everything has been transferred successfully without any issues.

-------

In conclusion, we have seen two different methods for converting an ISO file into a DMG format using nothing but built-in Unix utilities available straight from within terminal window of Ubuntu distribution. The first method involves manually executing series of commands while second option relies on third-party tool called DMGConverter which provides much more user-friendly interface along with additional features like support for multiple input/output formats.

Regardless of the approach you choose, remember to always exercise caution when working with compressed archives as small mistakes can lead to data loss or corruption. Therefore, make sure to backup your important files before proceeding with any conversion process!
