解决办法

①使用 wget 下载并添加公钥

方法一

wget -qO - https://packages.sury.org/php/apt.gpg | tee -a /etc/apt/trusted.gpg.d/php.sury.org.gpg

方法二

Shell Session 
wget -qO /etc/apt/trusted.gpg.d/sury-php.gpg https://packages.sury.org/php/apt.gpg

②从钥匙服务器获取公钥

Shell Session 
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B188E2B695BD4743

③检查源配置文件

确保/etc/apt/sources.list.d/php.list 文件中的源配置正确无误。
