“子进程安装前删除脚本返回错误退出状态2”错误，同时试图删除postgresql客户端-公共

Question

我正在使用Ubuntu10.04，并试图从我的计算机中删除postgresql客户端--常见，但我得到了以下错误：

E: postgresql-9.2: subprocess installed pre-removal script returned error exit status 2
E: postgresql-client-9.2: subprocess installed pre-removal script returned error exit status 2
E: postgresql-common: subprocess installed pre-removal script returned error exit status 2

我尝试过：sudo apt-get -f install，但也失败了：
