我搞砸了我的 raspbian (debian) 安装。为了解决这个问题，我将重新安装每个软件包。这很烦人（或者更确切地说：很慢），但总体上有效。
我绝对陷入困境的是重新安装我最需要的 PHP 软件包：
apt-get install php5-curl
Setting up php5-curl (5.4.4-14+deb7u10) ...
dpkg: error processing php5-curl (--configure):
subprocess installed post-installation script returned error exit status 10
由于其他 php5 模块也失败了，我不愿意删除安装后脚本——我需要删除其中几个才能安装 PHP。
为了查看安装后的问题，我手动运行了它：
pi@prodpi ~ $ sudo sh -x /var/lib/dpkg/info/php5-curl.postinst configure && echo &?
pi@prodpi ~ $ + set -e
+ inidir=/etc/php5/mods-available
+ [ configure = configure ]
+ inifile=curl.ini
+ sed -ne s/^; priority=\([0-9]\+\)$/\1/p /usr/share/php5/curl/curl.ini
+ priority=20
+ ucf /usr/share/php5/curl/curl.ini /etc/php5/mods-available/curl.ini
[2]+ Exit 10
仅运行最后一个命令给出：
pi@prodpi ~ $ sudo ucf -v /usr/share/php5/curl/curl.ini /etc/php5/mods-available/curl.ini
ucf: The new file is /usr/share/php5/curl/curl.ini
ucf: The Destination file is /etc/php5/mods-available/curl.ini
ucf: The Source directory is /usr/share/php5/curl
ucf: The State directory is /var/lib/ucf
The hash file exists
egrep [[:space:]]\/etc\/php5\/mods\-available\/curl\.ini$ /var/lib/ucf/hashfile
ucf: The new file is /usr/share/php5/curl/curl.ini
ucf: The Destination file is /etc/php5/mods-available/curl.ini
ucf: The Source directory is /usr/share/php5/curl
ucf: The State directory is /var/lib/ucf
The hash file exists
然而它确实以代码 20 退出，而不是 10 - 所以我不确定我是否真的在正确的位置寻找。
运行-d9显示：

我可以做什么来查找/解决安装后问题的根源？
