我正在尝试预先configurationredmine安装，并且被卡住了
debconf-set-selections pkg.selections 导致很多错误消息

如果在软件包安装完成后运行debconf-set-selections ，它就可以工作，但是我需要重新configuration软件包。
有人能解释我请正确的方法来做到这一点？
有时在去除软件包后， debconf数据库处于不一致的状态。 打开文件/var/cache/debconf/templates.dat并尝试find提及你的包的模板。 删除它们并使用debconf-set-selections再试一次。
尝试/usr/share/debconf/fix_db.pl
