Для исправления удаляем старый ключ и качаем новый, если не помогло, смотрим локальное хранилище ключей на наличие второго ключа DEB.SURY.ORG и удаляем тот, который просрочен
 rm -rf /etc/apt/trusted.gpg.d/sury.gpg
 apt-key del '''95BD4743'''


Качаем новый ключ
 wget -O /etc/apt/trusted.gpg.d/sury.gpg https://packages.sury.org/php/apt.gpg


Проверяем
