Well, you posted in the General > Getting Started section. You should post in the section for a specific device + OS. We need to know exactly what hardware and what OS before we can provide much help. There are many Debian derivatives that use apt, and multiple Pine devices that use that firmware package, including the PineNote, PinePhone Pro and Pinebook Pro.
If you do a web search on apt EXPKEYSIG you can find advice on fixing it, e.g.

Basically, your particular install has an old key and you need to get the new one.
