sudo apt install extlinux

DEB Package Installation

Navigate to the directory containing the downloaded DEB package using the terminal. Install the package using the dpkg utility:

sudo dpkg -i unetbootin_700-1~groovy1_amd64.deb

If dependency issues arise during installation, resolve them using the following command:

sudo apt --fix-broken install

This command automatically identifies and installs missing dependencies, completing the UNetbootin installation process. Alternative installation using apt directly handles dependency resolution automatically:

sudo apt install ./unetbootin_700-1~groovy1_amd64.deb

This method provides superior dependency management and reduces the likelihood of installation failures.

Method 3: Using Binary Executable

Downloading the Binary

The binary executable method offers maximum compatibility across different Linux distributions without requiring package management or repository modifications. This approach proves particularly valuable for systems with restricted package installation capabilities.

Download the Linux binary from the official UNetbootin website at unetbootin.github.io. Select the appropriate architecture version (typically unetbootin-linux64-702.bin for 64-bit systems) and save the file to your preferred directory.

Running the Binary

Make the downloaded file executable using the chmod command:

chmod +x ./unetbootin-linux64-702.bin

Launch UNetbootin by executing the binary file:

./unetbootin-linux64-702.bin

The application launches immediately without requiring system installation or modification. This method provides complete portability and can be executed from removable media if necessary.
