Suggest you seek support from Homebridge
I’d like to stick here
It seems that OSMC’s Debian doesn’t have the GPG command integrated. Am I right in that?
it’s available, as it is in all debian distros. Just not install by defaukt
Okay, it works! First I had to put in this:
sudo apt-get update
And then:
sudo apt-get -y install gnupg
Than I could successfully follow the install procedure from HomeBridge.
