@leanmarg Can you confirm you tried installing balena-etcher instead of balena-etcher-electron.
I see the docs is confusing, I'm updating it.

sudo apt install balena-etcher
[sudo] password for airobo:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package balena-etcher

Even in my case it ios not working,

@ranjitkathiriya

have you installed Etcher by this way: https://github.com/balena-io/etcher? For me, this works well on Ubuntu 22.04.2 LTS
But here you need to install curl before sudo apt-get install curl

Hi, I am facing the same issue, seems like apt-get cannot find the package.
curl is installed and all previous commands before the install are working. I tried both with the github guide and the one on Cloudsmith with the same result.

@danielkirch

you did it exact like this?

If you don't have curl installed (it is not installed by default):
sudo apt-get install curl

1. Add Etcher Debian repository:
curl -1sLf 'https://dl.cloudsmith.io/public/balena/etcher/setup.deb.sh' | sudo -E bash

2. Update and install:
sudo apt-get update sudo apt-get install balena-etcher-electron

Note:
works also with apt as well, but I would also suggest apt-get as well.

This instruction has last worked for me on Ubuntu 22.04.2 LTS.
