在 Ubuntu 16.04 上安装 PHP 7.x

在 Ubuntu 16.04 上安装 PHP 7.x

我知道这个问题已经被问过很多次了，但是我总是得到相同的答案，而这并不能解决我的问题。

提供的解决方案通常是这样的：

~$ sudo apt-get install software-properties-common python-software-properties;
~$ sudo add-apt-repository -y ppa:ondrej/php;
~$ sudo apt-get update;

大功告成！但不幸的是，我的情况并非如此。

因此，执行前面提到的步骤后，我尝试通过安装“任何”PHP 7.x 版本，apt但似乎找不到任何版本的 PHP 的软件包。

同样有趣的是，当我使用时，apt search似乎没有任何php版本的软件包

... etc

我错过了什么？

编辑：执行后apt-get purge php7.4消息（至少 PHP 7.4）已更改为以下内容：

~$ sudo apt-get install -y php7.4

对于任何感兴趣的人；

自 2021-06-10 起，Ubuntu xenial 16.04 不再支持 PHP。当我尝试在其他使用 16.04 的 VM 上安装 PHP 模块/版本时，我发现了这个问题，显然“找不到软件包”，而其他机器之前已经轻松安装了它们。

stackoverflow 上有一篇文章描述了这一点：https://stackoverflow.com/questions/67920506/unable-to-install-php-7-4-on-ubantu-16-04-even-with-ondrej-ppa-repository-in-apa
