See #2870

...but if you're running Raspberry Pi OS, you could just use Raspberry Pi Imager? https://www.raspberrypi.com/software/

You can still select "Use custom" in RPi Imager, if you want to use your own .img file.

is that also for a .iso image ?

Yes, see https://github.com/raspberrypi/rpi-imager/blob/qml/src/imagewriter.cpp#L589

@karllumpkins not dead at all you can install using https://github.com/Botspot/pi-apps
Or build it from source.

The balena-etcher-electron wasn't an official package and has been dropped as far as I know

Just out of curiosity (because I'm a curious chap), I did a bit of digging and it looks like pi-apps only has version v1.10.0 of Etcher, which is quite a bit behind the current version v1.12.7 ?
