无法将 PHP 升级到 7.3，因为没有可用的匹配包

Question

我无法在 ubuntu 16.04 从 7.2 升级到 php7.3，我运行以下命令：

sudo apt-get install python-software-properties
sudo LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt install php7.3

出现以下输出：

Building dependency tree

Note, selecting 'php7.3-mongodb' for regex 'php7.3'
Note, selecting 'php7.3-memcached' for regex 'php7.3'

和PHP -v 还是老版本

Answer 1

Ondřej removed support for 16.04 几天前：

As of this moment, all the packages for the Ubuntu 16.04 LTS (Xenial) have been removed from the repositories.

这解释了它为何上周对您有效，但今天无效。
