When you update Screenly through Balena, do you need to execute the following command in the HOST OS or MAIN terminal?
$ bash <(curl -sL https://www.screenly.io/install-ose.sh)
Also, Screenly update asks thing like Networkmanageretc. what are the recommended settings?
Sorry being total new to this!
Balena is different. In essence, you manage your device(s) from your workstation/laptop instead of directly on the device. You can read more about code deployments here.
In short, it usually looks something like this:
$ cd /path/to/code/base
$ git pull
$ git push balena master
Balena will then build a new image and push it out to your device(s).
