有一些软件包无法被安装。如果您用的是 unstable 发行版，这也许是
因为系统无法达到您要求的状态造成的。该版本中可能会有一些您需要的软件

apt-get will automatically solve the software package dependency problem. It is recommended that you try to execute
sudo apt-get update
and then try to install the software package you need

This kind of problem usually occurs because the software source is not configured properly

I personally use the China server in Ubuntu Software (as shown in the picture), and there is no problem that cannot be solved by dependencies.

It will automatically update after switching here, no need to manually apt-get update

The PHP version in the Ubuntu 16.04 software source is 7.0.
If you want to install LAMP, you can do this:
sudo apt-get install apache2 php7.0 php7.0-mysql mysql-server

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info.bak //Now rename the info folder
sudo mkdir /var/lib/dpkg/info //Create a new info folder
sudo apt-get install libapache2-mod-php7.0
sudo mv /var/lib/dpkg/info.bak /var/lib/dpkg/info
