可能在運行後

add-apt-repository ppa:ondrej/php

透過運行刪除先前的來源

sudo add-apt-repository --remove ppa:ondrej/php
sudo apt update

您需要如下編輯儲存庫來源檔案：

sudo nano /etc/apt/sources.list

並輸入

deb https://ppa.launchpadcontent.net/ondrej/php/ubuntu jammy main

然後運行

sudo apt update

之後您現在應該可以以 8.3 為例安裝您的 php 版本

sudo apt install php8.3

如果您已經安裝了其他一些 php，您可能需要使用
更改為版本

sudo update-alternatives --config php

然後按照提示操作。

您也可以考慮安裝以下擴充功能

sudo apt install php8.3-curl php8.3-gd php8.3-intl php8.3-simplexml php8.3-dom php8.3-mysql php8.3-mbstring php8.3-xml php8.3-gd php8.3-curl php8.3-mysqli php8.3-zip
