我按照下面的命令顺序安装了 Apache 后，出现了错误：/usr/sbin/apache2ctl: 171: /usr/sbin/apache2ctl: /usr/sbin/apache2: not found。经过一番谷歌搜索，我发现它是 Apache2 依赖项的一部分，但显然它缺失了。有人知道是哪个依赖项吗？
命令序列：
sudo apt-get install apache2.2-common
sudo apt-get install apache2
sudo apache2ctl start -k
在谷歌搜索了一番之后，我认为我应该尝试一下，
sudo service apache2 start但结果却出现了错误：No apache MPM package installed。我尝试使用命令来安装该包sudo apt-get install apache2-mpm-prefork。我在这里发布了结果。

答案1
您可以使用 dpkg 命令来找出文件所属的包
dpkg -S /path/to/file
例如：
$ dpkg -S /usr/sbin/apache2ctl
apache2.2-common: /usr/sbin/apache2ctl
该文件属于包apache2.2-common。
答案2
我设法通过删除所有带有“apache”的软件包，然后再次安装 Apache 来解决此问题。
sudo apt-get install -f
sudo dpkg --purge gezgsdgdfg*
sudo apt-get install -f
sudo apt-get install apache2
