Application Expiration Date

Hello @arfenarf, thank you for letting us know about this - and I'm sorry to learn of the issue!

I believe this is related to a change we made to our GPG key a little while back. If you follow the installation steps here, that should fix the issue (as well as get you an updated copy of 1Password for Linux). But if you try this and the issue persists, feel free to let me know and I'll be happy to dig deeper. We'll make sure this gets sorted out! 😃
