我的 debian 服务器上的 apache2 软件包已损坏，因此我首先卸载所有 apache2 相关软件包。现在一切似乎都已正确卸载。
dpkg -l | grep 'apache'不返回任何内容
但是，我似乎无法安装apache2...
和apt-get：
sudo apt-get install apache2

我该如何解决这个问题并让 Apache 重新工作？

答案1
根据aptitude，一个名为的 Apache 依赖项libaprutil1安装在比存储库中提供的版本更新的版本中：
The following packages have unmet dependencies: libaprutil1-dbd-sqlite3 : Depends: libaprutil1 (= 1.4.1-3) but 1.5.4-1+b1 is installed. libaprutil1-ldap : Depends: libaprutil1 (= 1.4.1-3) but 1.5.4-1+b1 is installed.
您可以尝试使用以下方法找出该包的来源apt-cache policy：
apt-cache policy libaprutil1
libaprutil1=1.5.4-1+b1似乎来自 Debian sid...您是否有机会尝试从 sid 存储库安装 Apache？这似乎不是一个好主意...如果您想要更新的 Apache 版本，我建议升级到 Debian 杰西。
请将 的输出附加apt-cache policy到您的问题中（当您这样做时，也将 的输出附加到您的问题中cat /etc/apt/sources.list）；您可能sources.list包含来自 wheezy 和 sid 存储库的 URL，这将是一件坏事。
您可以尝试删除较新的libaprutil1软件包：
aptitude purge libaprutil1
然后再次尝试安装 Apache：
aptitude install apache2
答案2
libaprutil1是导致问题的包（很可能是它的依赖项libapr1）。你需要：
testing/security从你的/etc/apt/sources.list;中删除该行更新包缓存：
sudo apt-get update删除
libaprutil1并libapr1：sudo aptitude remove libaprutil1 libapr1（以及任何依赖于它们的包）
然后安装
apache2：sudo aptitude install apache2
