The latest version of the tool arrives almost a year to the day since we first introduced you to this easy-to-use image writer tool from Balena.
The new release adds a boat load of improvements to the image writing tool that its developers say make it “a much more stable and reliable” than before.
A Recap of Etcher Features
Balena is the company steering development of the app and they say, over the course of its releases to date, Etcher has been used to write over one million images to SD cards & USB drives.
As an Electron app Etcher is also a true cross-platform tool that you can run on Windows, macOS and Linux. Regardless of which OS, Etcher can write
.zip files to USB drives and SD cards.
The main interface is dead simple to use too: you select an image, select a drive (the built in drive picker is designed to avoid you making mistakes and overwriting a hard drive, etc) and hit the Flash button.
Use the validated burning option to double-check your image after flashing it, so that you’re not left faffing about trying to boot from a dud drive.
No sign of some previously planned features, like support for creating multi-boot USB sticks, or enabling persistent storage on Ubuntu images.
- Support for creating multi-boot USBs
- Support for persistent storage on Ubuntu images
- Registered Etcher as handler for *.img and *.iso files
It’s not just the GUI client that’s gotten an update though. Etcher 1.0 also sees the first experimental release of the Etcher CLI.
The Etcher CLI lets you to write images and validate flashes from the command line. As it doesn’t rely on the Electron framework, it’s a smaller download and install size. Its developers also tout the ability for users to write custom scripts using the CLI to “perform tasks such as multi-writes.”
How to install Etcher on Ubuntu
Etcher is available to download for Windows, macOS and Linux from the Etcher.io website as well as from the GitHub release page below:
Etcher’s Linux builds are provided in the AppImage package format.
AppImages are self-contained runtimes that do not require manual installation or root (but do require you necessary permissions to run).
And since AppImage will run on pretty much any distro out there, you only need to download it and double-click on it to run:
If you prefer to install your apps in a more traditional way, i.e. using apt, you can install Etcher on Ubuntu from a repository.
Getting the repo set up is a bit bit more involved than using the AppImage, but it does ensure you get future Etcher updates automatically through the Software Updater tool.
To add the Etcher repo first open the Software & Updates app:
Select the ‘Other Software’ tab in Software & Updates 
Click ‘Add’  and paste the following the entry field of the box that appears:
deb https://deb.etcher.io stable etcher
Click ‘Add Source’  to confirm the change, then close Software & Updates. You’ll likely be prompted to update your software sources.
You can also do this using the terminal with the command:
echo "deb https://deb.etcher.io stable etcher" | sudo tee /etc/apt/sources.list.d/balena-etcher.list
The next step is to add the repository key. This allows Ubuntu to verify that packages installed from the repository are made by who they say they are. You have to add this key to be able to install Etcher; Ubuntu will disable unsigned repos.
Open a new Terminal window, paste the following command, and then hit return/enter:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 379CE192D401AB61
Finally, update your packages list and install the app:
sudo apt update && sudo apt install balena-etcher-electron
That’s it; launch Etcher from the Applications grid or your preferred Linux app launcher and follow the on-screen instructions.
