Ubuntu 16.04 上的 php 和 libssl1.1 安装损坏

Question

我一直在使用Ubuntu 16.04。最近我对 PHP 安装做了一些实验，恐怕我已经严重破坏了东西。我试过

sudo apt install php7.0

但它显示了依赖性和损坏的包错误

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.0 : Depends: libapache2-mod-php7.0 but it is not going to be installed or
                   php7.0-fpm but it is not going to be installed or
                   php7.0-cgi but it is not going to be installed
          Depends: php7.0-common but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

接下来，我跑了

sudo apt install php7.0-common

响应是

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.0-common : Depends: libssl1.1 (>= 1.1.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

似乎libssl1.1缺少依赖项，所以我尝试手动安装它

sudo apt install libssl1.1

这是回应

Package libssl1.1 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 'libssl1.1' has no installation candidate

我现在有点卡住了。我是否永久破坏了我的操作系统？

我已经通过手动安装解决了这个问题libssl。

wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb
sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb
