我已将系统升级到 ubuntu 16.04 LTS，现在我已发布此更新版本安装 PHP 7 并删除 PHP 5，如何在 ubuntu 16.04 LTS 上安装 PHP 5.4？
我尝试过:
sudo apt-get install php5
我得到了这个错误:
Reading package lists... Done
Building dependency tree
Reading state information... Done
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
E: Package php5 has no installation candidate
最佳答案
Ubuntu 16.04 附带 PHP7，没有 PHP5 软件包。 删除所有 php7 软件包:
sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "
新的购电协议(protocol)
sudo add-apt-repository ppa:ondrej/php
更新包:
sudo apt-get update
安装 PHP:
sudo apt-get install php5.6
检查 PHP 版本:
php -v
关于php - php5 软件包在 Ubuntu 16.04 LTS 上没有安装候选，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36910794/
