我最近在Linux Mint操作的笔记本电脑中安装了PHP7的LAPM堆栈。现在，我想使用PHP5.6。无需搜索更多信息，我只是使用以下命令删除了LAMP堆栈的所有内容。
然后，我使用whereis命令查找有关php，apache，mysql的所有信息并手动删除。再次执行sudo apt-get autoremove命令。
现在，我重新启动笔记本电脑，以确保在安装LAMP堆栈时没有任何后台操作导致冲突。
我计划安装php 5.6和7.2的双重实例。这就是为什么我使用以下命令添加了新的PPA。
现在，我尝试使用以下命令安装Apache：sudo apt-get install apache2，并在命令面板中找到以下错误脚本：
