Hi with all. I have this problem when i intented update in debian:
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://artifacts.chirpstack.io/packages/3.x/deb stable InRelease: The following signatures were invalid: EXPKEYSIG CFF064C9D12ECB34 Orne Brocaar email@example.com
What’s the meaning of EXPKEYSIG, and this affects to the communication between the app-server and the node?
