我在虚拟机上安装了 18.04。我想更新到 php8.1
我的机器上已经有 PPA php 存储库：
sudo add-apt-repository ppa:ondrej/php
我可以看到有一个文件：
# ls -l /var/lib/apt/lists/ppa.launchpad.net_on*
-rw-r--r-- 1 root root 20811 Jun 15 21:41 /var/lib/apt/lists/ppa.launchpad.net_ondrej_php_ubuntu_dists_bionic_InRelease
我努力了：

2023 年 6 月 15 日，Ondřej Surý 的 PPA 中不再支持 Ubuntu 18.04，因为该版本的 Ubuntu 不再受支持。根据PPA 登陆页面上的描述：
... 仅支持 PHP 版本 (http://php.net/supported-versions.php) 支持的 Ubuntu 版本 (https://wiki.ubuntu.com/Releases) 已提供。不要要求提供终止使用的 PHP 版本或 Ubuntu 版本，它们不会提供。
如果你真的必须在 Ubuntu 18.04 服务器上使用 PHP 8.1，那么你唯一的半支撑前进的道路是使用 Docker 容器。但是，如果 Docker 不再为 18.04 提供其工具，那么您需要考虑从 18.04 更新到更新的版本。
