我在Debian上安装apache2时遇到问题。当我尝试安装时，我得到了
sudo apt-get install apache2
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package apache2
这是我的回购（/etc/apt/sources.list）

删除每行开头的＃字符。
deb repo用于二进制包
deb-src repo用于源包

正如@nurza所说，你必须启用二进制存储库，擦除＆＃34;＃＆＃34;在以#deb开头的行上。 /etc/apt/sources.list上的第一行应该有：
deb http://debian.mirrors.ovh.net/debian/ wheezy main
