我一直在尝试为我的个人项目生成 deb 文件。该项目使用 sbt 和 sbt-native-packager 生成 deb 文件，我将其安装在我的服务器上。
我在我的控制存档中添加了templates、config和postinst脚本（并确认它们已解压），但 debconf 似乎没有检测到新模板。 sudo debconf-show t-budget出现空白并且每次db_input返回10 "t-budget/<template>" doesn't exist。
除了将文件放在我的控制存档中之外，我还需要做些什么才能将这些模板添加到数据库中吗？
旁注：我提到 sbt-native-packager 因为我没有直接使用 deb 创建工具可能相关，但看起来我所拥有的应该可以工作，如果这是该工具的限制，我想知道问题是什么，以便我可以解决它。
这些是我尝试使用的配置文件：

/var/lib/dpkg/info/t-budget.templates：
Template: t-budget/database/ip
Type: string
Default: localhost
Description: What is the host of your PostgreSQL server?
T-Budget needs a postgresql server to store it's data.
You can host one locally or have it connect over the network.
Enter the host's domain name or IP address.
Note: If the database is not the localhost, the install script will not be able to configure it automatically.
Template: t-budget/database/name
Type: string
Default: budget
Description: What is the name of your database?
A single postgres server can host several isolated databases.
It is recommended that T-Budget run on it's own database to maximize security and data integrity.
Template: t-budget/database/username
Type: string
Default: t-budget
Description: What is the PostgreSQL username?
T-Budget should use an isolated username with limited permissions to the rest of the system.
To create a new user, enter a username which is not yet in use.
Template: t-budget/database/password
Type: password
Description: What is the PostgreSQL password?
If creating a new user, it will be created with this password.
If using an existing user, this password will need to match the current password of that user.
Template: t-budget/hostnames
Type: string
Description: What is the hostname of your server?
What is the domain name of the server users will use to access T-Budget?
Used for security protocols.
You can input multiple hostnames seperated by a space.
You can also prefix your hostname with a '.' to include all subdomains in addition to the hostname.

答案1
因此，在查看了官方存储库中的工作示例并逐一使其与我的匹配后，我发现了问题：
db_purge
此行将从数据库中删除所有模板。我添加它是因为我正在复制另一个示例，所以我不确定该示例是如何工作的，但删除这一行解决了问题。
