Questo errore si verifica perché sury.org ha cambiato la chiave della firma digitale per Debian e per risolvere il problema è necessario scaricare la nuova chiave.

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

Dopo aver eseguito questo comando, puoi aggiornare tutti i pacchetti Debian:

apt update && apt upgrade

Quelli che usano WordOps eseguirà la riga di comando:

wo stack upgrade

Tutto funzionerà senza problemi nell'aggiornamento dei pacchetti su Debian.
