Can't update to FTL 5.9 Final: "Error: Unable to update package cache."

That's an issue with updating your OS rather than with Pi-hole: Your OS is informing you that the repository is now oldstable. Answering [y]es to that question or running sudo apt-get update --allow-releaseinfo-change should allow your OS to reflect that change and continue.

There might be more issues with your OS, but please try what is suggested in the link above and try sudo apt upgrade again.
