Package php5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

我现在该怎么办？

Answer 1

Ubuntu 16.04 LTS 附带 PHP 7.0。要安装它，您需要运行：

sudo apt-get install php

或者更确切地说，选择一个特定的 PHP Web SAPI，很可能您需要对 Apache2 的支持：

sudo apt-get install libapache2-mod-php php

或 PHP FPM

sudo apt-get install php-fpm php

如果您特别需要 PHP 5.x，则需要使用ppa:ondrej/php和安装 PHP 5.6 for Apache2：

sudo apt-get install php5.6 libapache2-mod-php5.6

Answer 2

16.04 官方存储库中没有 PHP 5。安装 14.04 系统，或使用此 PPA。
