Denne fejl opstår, fordi sury.org ændrede den digitale signaturnøgle til Debian, og for at løse problemet skal du downloade den nye nøgle.

apt-key adv --fetch-keys https://packages.sury.org/php/apt.gpg

Efter at have kørt denne kommando, kan du opdatere alle Debian-pakker:

apt update && apt upgrade

Dem, der bruger WordOps, kører kommandolinjen:

wo stack upgrade

Alt vil fungere uden problemer med at opdatere pakker på Debian.
