Debian :重新安装apache2

Question

apache2包在我的debian服务器上被破坏了，所以我开始卸载所有与apache2相关的包。现在所有的东西似乎都被正确地卸载了。

dpkg -l | grep 'apache'什么都不回

然而，我似乎无法安装apache2.

使用apt-get：

sudo apt-get install apache2

我如何解决这个问题，让Apache重新开始工作呢？

Answer 1

根据aptitude，名为libaprutil1的Apache依赖项安装在比存储库中可获得的更新版本中：

以下软件包有未满足的依赖关系:libasrutil1-DBD-sqlite 3: libaprutil1 (= 1.4.1-3)，但是安装了1.5.4-1+b1。Librirutil1-ldap:取决于: libaprutil1 (= 1.4.1-3)，但是安装了1.5.4-1+b1。

您可以尝试用apt-cache policy找出这个包的来源：

apt-cache policy libaprutil1

libaprutil1=1.5.4-1+b1似乎来自Debian ..。您是否尝试过从sid存储库中安装Apache？这似乎不是个好主意..。如果您想要更新的Apache版本，我建议升级到Debian jessie。

请将来自apt-cache policy的输出附加到您的问题中(当您正在进行时，也包括来自cat /etc/apt/sources.list的输出)；您的sources.list可能包含来自wheezy和sid存储库的URL，这将是一件坏事。

您可以尝试删除更新的libaprutil1包：

aptitude purge libaprutil1

然后再次尝试安装Apache：

aptitude install apache2

Answer 2

libaprutil1是导致问题的包(很可能是它的依赖项，libapr1)。你需要：

• 从您的testing/security中删除/etc/apt/sources.list行；
• 更新包缓存: sudo apt-get更新
• 删除libaprutil1和libapr1：sudo智能删除libaprutil1 libapr1 (以及依赖它们的任何包)
• 然后安装apache2：sudo智能安装apache2
