安装5.6和7.4正确的姿势为：

sudo apt update
sudo apt install software-properties-common ca-certificates lsb-release apt-transport-https
sudo sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
wget -qO - https://packages.sury.org/php/apt.gpg | sudo apt-key add -
sudo apt update
sudo apt-get install libapache2-mod-php5.6
sudo apt-get install libapache2-mod-php7.4

多版本切换可以用下面的命令：
sudo update-alternatives --config php

也可以直接在Web Server里勾选：
