使用debconf帖子创建deb包

Question

我在创建deb packgaes方面做得很好。我创建了为用户提供答案的deb包。但是当我运行sudo apt install ./mypackge.deb时

我得到了同样的错误

我尝试了config/postinst的不同变体，使用了debconf手册中的示例，但得到了相同的错误。

 Can't exec "/var/lib/dpkg/info/test.config.....

如果你能指出我的错误就好了。技术

我假设您的.deb缺少config maintainer脚本(可能还缺少templates文件)。你可以向dpkg-deb -I test.deb查询。
