之前我曾意外地从安装中删除了 Apache，以尝试删除 LDAP 服务器上不需要的软件包。我没有意识到的是，我还安装了 Fusion Directory，现在我无法重新安装 Apache 或 Fusion Directory，因为每次尝试使用 apt/dpkg 进行操作时都会出现错误：
ckilgore@ubuntu-ldap-server:/etc/apache2/conf-available$ sudo apt install apache2
Reading package lists... Done

apache2 is already the newest version (2.4.18-2ubuntu3.1).
The following packages will be REMOVED:

1 not fully installed or removed.
After this operation, 6,822 kB disk space will be freed.

Removing fusiondirectory (1.0.8.8-3ubuntu2) ...
apache2_invoke fusiondirectory postrm: No action required
apache2.service is not active, cannot reload.
invoke-rc.d: initscript apache2, action "reload" failed.
dpkg: error processing package fusiondirectory (--remove):
subprocess installed post-removal script returned error exit status 1
Errors were encountered while processing:
fusiondirectory
E: Sub-process /usr/bin/dpkg returned an error code (1)
我真正想做的是完全卸载 Apache 和 Fusion Directory，重新安装并重新导入 Fusion Directory 的配置。但是，由于存在此问题，我无法做到这一点。解决此问题的最佳方法是什么？
以下是来自 syslog 和 apt log 的条目

答案1
您可以手动编辑文件/var/lib/dpkg/info/fusiondirectory.postrm修复删除错误。如果 Apache 仍在运行，请停止它，然后使用 root 权限打开该文件并找到其中的部分：
if [ -x /usr/sbin/apache2 ]; then
if [ -x /usr/sbin/invoke-rc.d ]; then
invoke-rc.d apache2 reload
else
/etc/init.d/apache2 reload
fi
fi
评论一下然后尝试
sudo apt-get install -f
修复错误或只是
sudo apt-get remove fusiondirectory
最后删除 fusiondirectory。
