Zoeken op apt key sury.org of apt signatures were invalid: EXPKEYSIG B188E2B695BD4743 geeft voldoende resultaten, maar alleen
apt-key adv --keyserver keys.gnupg.net --recv-keys B188E2B695BD4743
of
curl -sSL -o /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
lost het probleem niet altijd op.
Soms bleek het nodig om eerst de bestaande sleutel te verwijderen:
apt-key del B188E2B695BD4743
gevolgd door toevoegen van de nieuwe sleutel.
