我在 15.10 上安装了 lamp。它正常工作。昨天我将我的 ubuntu 计算机从 15.10 更新到了 16.04。我尝试访问 localhost，但没有成功。
我尝试过service apache2 restart并收到以下错误：
● apache2.service - LSB: Apache2 web server

明白了，伙计们！别担心！
我了解到 16.04 附带的是 php 7.0 而不是 5.0。我猜是我为 apache 安装了 php 5.0 的模块。
安装php7.0 apache模块：
sudo apt-get install libapache2-mod-php7.0
禁用 php5 模块，因为我们没有 php5.0：
sudo a2dismod php5
启用php7模块：
sudo a2enmod php7.0
重新启动Apache：
sudo service apache2 restart
就这样吧，伙计们
