我是个新手，在尝试重新安装 apache2 和 php 时弄乱了服务器，我在这个论坛和互联网上进行了广泛的搜索，但没有找到解决类似问题的方法。目前我的网络服务器下载文件而不是打开网页，所以我正在尝试重新安装 apache2。
这些是我遇到的主要错误：
E: Unable to correct problems, you have held broken packages.
E: Package 'liblua5.2-0' has no installation candidate
使用 apt-get：
# apt-get install apache2

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:
apache2 : Depends: apache2-bin (= 2.4.23-5.0+deb.sury.org~precise+2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
具有以下能力：
# aptitude install apache2

我尝试使用以下组合重置包列表：
# apt-get update
# apt-get upgrade
# apt-get dist-upgrade
我还放了一个 source.list 的干净副本：
# curl https://repogen.simplylinux.ch/txt/precise/sources_e2fd9ed56e2187914ef4ae006a33c9cc299a8ee8.txt | sudo tee /etc/apt/sources.lis
可能是其他地方列出了软件包来源？我可能添加或删除了一些重要的内容，但不记得在哪里了。
