add repo etcher

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

We continue updating the list of available software from the repositories available on our team. We will do this with this other command:

update repositories

sudo apt update

After the update, we only have to use the install command:

install etcher with apt

sudo apt install balena-etcher-electron

When the installation is finished, we can find the launcher of this program in our team.

We will also have the possibility of download the latest version today from Etcher as AppImage file from your website. We can do this using wget from the terminal (Ctrl + Alt + T):

download appimage

wget https://github.com/balena-io/etcher/releases/download/v1.5.120/balena-etcher-electron-1.5.120-linux-x64.zip

Once the download is finished, we will have to go to the location where we save the Etcher zip file to unzip it:

unzip file with appimage

unzip balena-etcher-electron-1.5.120-linux-x64.zip

Then we only have give execute permissions to the AppImage file:

chmod +x balenaEtcher-1.5.120-x64.AppImage
