Signature problem with apt-get update

[becksen]

I’ve used another repo:

APT Repo Public Key Expiration & Update

you can get the stable version from jfrogio also echo ‘deb https://openhab.jfrog.io/openhab/openhab-linuxpkg stable main’ | sudo tee /etc/apt/sources.list.d/openhab2.list sudo apt update should be the correct way, as swamiller said (APT Repo Public Key Expiration & Update), the repo has moved you really shouldn’t use [trusted=yes]

This seems to work.
