无法访问本地主机，检查apache状态时出错

Question

我在运行Linux Mint Maya。当我在浏览器中输入http://localhost/时，会收到一条“无法连接”的消息。我尝试过卸载和重新安装apache，但是没有成功。当我在终端中输入sudo service apache2 status时，我得到了/etc/init.d/apache2: 51: .: Can't open /etc/apache2/envvars

以下是/etc/apt/sources.list的内容

deb http://packages.linuxmint.com/ maya main upstream import
deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ precise partner

# deb http://archive.getdeb.net/ubuntu precise-getdeb apps
# deb http://archive.getdeb.net/ubuntu precise-getdeb games

当我运行Update时，我得到了一个错误，但我认为它并不重要，所以我一直忽略它。以下是错误：

There is no public key available for the following key IDs:
1397BC53640DB551Failed to fetch http://ppa.launchpad.net/heyarje/libav-       11/ubuntu/dists/precise/main/source/Sources  404  Not Found

我做错了什么？

Answer 1

我让阿帕奇工作了。我不完全确定怎么做，但我认为这与运行更新发行版有关。在此之后，我能够运行与之前推荐的命令相同的命令，这一次，它们起作用了。

Answer 2

这可能与旧的配置文件有冲突。试着：

sudo apt-get purge apache2
sudo apt-get install apache2
