我無法將 nginx PHP 版本升級到 ubuntu 16 上的最新版本

Question

我試過升級PHP版本。 但我只是得到錯誤。

我試過這個教程。

apt update
apt upgrade

apt install software-properties-common
add-apt-repository ppa:ondrej/nginx

apt update
apt upgrade

apt install php8.0 php8.0-cli php8.0-fpm php8.0-apcu php8.0-opcache 
php8.0-common php8.0-pear php8.0-curl php8.0-zip php8.0-mcrypt php8.0-mysql 
php8.0-mbstring php8.0-xml php8.0-gd php8.0-gmagick php8.0-imagick 
php8.0-xmlrpc php7.3-maxminddb

但我得到這個錯誤。

嘗試apt full-upgrade和apt upgrade以及最后一個命令apt get update嘗試這三個命令，然后重新啟動機器它將解決。

Answer 2

如ppa 描述中所述：

僅提供受支持的 PHP ( http://php.net/supported-versions.php )版本( https://wiki.ubuntu.com/Releases )。

Ubuntu 16.04 自 2021 年 4 月起不再受支持，因此我認為 php 8.0 也不再有 xenial 分支。 我建議將 Ubuntu 升級到版本。 20.04 LTS 以便能夠使用 php 8.0
