Popsicle is a free and open-source USB flasher for creating multiple bootable drives simultaneously. This Linux utility supports parallel writing to several USB devices. It offers both graphical and command-line interfaces.

Popsicle works with USB 2.0 and USB 3.0 ports. It handles ISO and IMG file formats. System76 developed this tool as the default flashing utility for Pop!_OS. The application runs on Rust programming language with GTK framework.

Install Popsicle on Ubuntu-Based Systems

Pop!_OS includes Popsicle by default. Ubuntu users must add an external repository.

Add the official System76 PPA and install the packages:

$ sudo add-apt-repository ppa:system76/pop
$ sudo apt update
$ sudo apt install popsicle popsicle-gtk
$ sudo add-apt-repository -r ppa:system76/pop

The final command removes the repository. This prevents Pop!_OS upgrade notifications.

Note: Remove the PPA after installation to avoid unwanted system upgrade prompts. Add it again when updating Popsicle to newer versions.

If the System76 PPA fails, use the alternative repository:

$ sudo add-apt-repository ppa:apandada1/popsicle
$ sudo apt update
$ sudo apt install popsicle popsicle-gtk
Warning: The System76 PPA may not support all Ubuntu versions. Use the alternative PPA for newer Ubuntu releases.

Create Bootable USB Using Popsicle GUI

Launch Popsicle from your application menu. It may appear as USB Flasher in search results.

Connect your USB drives to the computer. Click Choose Image and select your ISO or IMG file. The device list displays all connected USB drives.

Select the target USB devices from the list. Multiple drives can be selected for parallel flashing. Click Next to begin the process.

Progress bars show completion status for each drive. The interface updates automatically when devices are added or removed.

Tip: Use the built-in hash checker before flashing. Select SHA256 or MD5, then click Check to verify your ISO file integrity.

Wait for the process to complete. Remove the drives safely once finished.

Create Bootable USB Using Popsicle CLI

Run Popsicle from the command line with the image file and device path:

$ sudo popsicle /path/to/image.iso /dev/sdX

Replace /dev/sdX with your actual USB device path. Use lsblk to identify the correct device.

Flash all connected USB devices with a single command:

$ popsicle -a /path/to/image.iso

The -a flag targets all detected USB drives simultaneously.

View available command options:

$ popsicle --help
Note: CLI mode provides additional flags for unmounting devices, verification checks, and skipping confirmation prompts.

Uninstall Popsicle

Remove the PPA repository first:

$ sudo add-apt-repository -r ppa:system76/pop

Remove the installed packages:

$ sudo apt remove popsicle popsicle-gtk

Clean up residual configuration files:

$ sudo apt autoremove
