15.10 升级到 16.04 后 PHP 崩溃

我意外地升级了我的系统而不是直接进行更新，而且我的 moodle 无法工作，因为 PHP 乱了。

它告诉我有未满足的依赖关系，并且 PHP5-cli 存在问题。

我该如何修复我的 php？我似乎无法修复依赖项。

运行时sudo dpkg --configure -a我遇到很多依赖问题 - 未配置。

sudo apt-get install -f我明白了

答案1

我遇到了同样的问题，我升级到 16.04 后，尝试通过安装基本 LAMP 包来运行 joomla，这时就开始发生这种情况。
无法安装任何包，也无法删除libapache2-mod-php5

删除 libapache2-mod-php5
错误：模块 php5 不存在！

经过一番 Google 搜索和思考后，我猜测 Apache 仍在使用 php5 是我的问题的一部分。

我不确定这是否是解决问题的正确方法，但我设法通过执行以下操作解决了此问题：

cd /etc/apache2/mods-enabled
sudo mv php5.conf php5.conf.old
sudo mv php5.load php5.load.old
sudo apt-get purge libapache2-mod-php5
sudo apt-get update
sudo apt-get upgrade

这解决了问题，我可以再次愉快地安装和删除软件。

也许有人比我聪明，可以解释为什么这样做有效，或者提出一个更优雅/更合适的解决方案。

无论如何，我希望这会有所帮助。

问题是你不再使用 PHP 5，而是运行 PHP7。你可能需要为新的 PHP7 更新一些 PHP 插件和文件。php.ini 现在位于 /etc/php/7.0 而不是 /etc/php5。你可能需要更改 apache 或 moodle 中的内容以反映此更改
