我正在尝试在 Ubuntu 22.10 上安装 php，我曾经能够执行“
apt install php当我运行 install php 时，我得到的是：
root@backups:/# apt install php
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
php8.2 : Depends: libapache2-mod-php8.2 but it is not installable or
php8.2-fpm but it is not installable or
php8.2-cgi but it is not installable
Depends: php8.2-common but it is not installable
E: Unable to correct problems, you have held broken packages.
我真的不在乎我能得到哪个版本的 php，只要它是 7 或 8，我试过很多指南，他们都告诉你要么添加这个（http://ppa.launchpad.net/ondrej /php/ubuntu/pool/main/p/php8.1/) repository （这不起作用）或者只是运行 apt install，这也不起作用。或者它的一些变体。
我可以安装任何程序，除了 PHO 或 PHP 相关的依赖项或包。
安装依赖时我得到：
root@backups:/# sudo apt install php8.1-fpm

添加 ppa:ondrej/php 存储库导致：
root@backups:/var/www/snipeit# sudo add-apt-repository ppa:ondrej/nginx-mainline

继续只是在更新时抛出一个错误
E: The repository 'https://ppa.launchpadcontent.net/ondrej/nginx-mainline/ubuntu kinetic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
我猜这个问题是由于 22.10 相当新，但我一直安装最新版本的 Ubuntu 并且安装程序从来没有问题，我认为这就是 Linux 的全部意义，稳定可靠。
我可以重新安装旧版本，但我想尽可能避免这种情况，因为我在那台机器上运行了更多服务。
我真的推荐通过 Ondřej Surý 的 PPA 安装 PHP
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt search php
您不仅可以安装 PHP，还可以安装其大部分流行的 PECL 包。
