我正在尝试在vultr的Ubuntu 22.04服务器上安装LEMP。我可以安装Nginx sudo apt install -y nginx-没有问题。
但是当我试图通过运行这些命令来安装php8.0时

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

我一直收到错误The repository 'https://ppa.launchpadcontent.net/ondrej/php/ubuntu jammy Release' does not have a Release file.
下面是运行sudo add-apt-repository ppa:ondrej/php命令后得到的结果

root@ubuntu:~# sudo add-apt-repository ppa:ondrej/php
