debconf not finding templates

I've been trying to generate a deb file for a personal project of mine. The project uses sbt and sbt-native-packager to generate a deb file which I will install on my server. I added a templates, config, and postinst script to my control archive (and confirmed that they are unpacked) but they debconf doesn't seem to detect the new templates. sudo debconf-show t-budget comes up blank and every db_input returns 10 "t-budget/" doesn't exist. Is there something I need to do to add these templates to the database besides have the files in my control archive? Side note: I mentioned sbt-native-packager because it might be relevant that I'm not directly using the deb creation tools, but it looks like what I have should work and if this is a limitation of the tool, I'd like to know what the problem is so I could fix it. These are the config files I'm trying to use: $ ls -lht /var/lib/dpkg/info/t-budget.* -rw-r--r-- 1 root root 27K Sep 4 21:54 /var/lib/dpkg/info/t-budget.md5sums -rw-r--r-- 1 root root 20K Sep 4 21:54 /var/lib/dpkg/info/t-budget.list -rw-r--r-- 1 root root 1.1K Sep 4 20:51 /var/lib/dpkg/info/t-budget.conffiles -rwxr-xr-x 1 root root 815 Sep 4 20:51 /var/lib/dpkg/info/t-budget.config -rwxr-xr-x 1 root root 2.9K Sep 4 20:51 /var/lib/dpkg/info/t-budget.postinst -rwxr-xr-x 1 root root 100 Sep 4 20:51 /var/lib/dpkg/info/t-budget.postrm -rwxr-xr-x 1 root root 1.9K Sep 4 20:51 /var/lib/dpkg/info/t-budget.preinst -rwxr-xr-x 1 root root 2.9K Sep 4 20:51 /var/lib/dpkg/info/t-budget.prerm -rwxr-xr-x 1 root root 1.6K Sep 4 20:51 /var/lib/dpkg/info/t-budget.templates /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. /var/lib/dpkg/info/t-budget.config: #!/bin/sh set -e # Source debconf library. . /usr/share/debconf/confmodule db_version 2.0 echo "configuring..." 1>&2 db_clear echo "CLEAR: $RET" 1>&2 db_purge echo "PRUGE: $RET" 1>&2 db_input high t-budget/database/ip || true echo "INPUT high t-budget/database/ip: $RET" 1>&2 db_input high t-budget/database/name || true echo "INPUT high t-budget/database/name: $RET" 1>&2 db_input high t-budget/database/username || true echo "INPUT high t-budget/database/username: $RET" 1>&2 db_input critical t-budget/database/password || true echo "INPUT critical t-budget/database/password: $RET" 1>&2 db_go echo "GO: $RET" 1>&2 db_input critical t-budget/hostnames || true echo "INPUT critical t-budget/hostnames: $RET" 1>&2 db_go echo "GO: $RET" 1>&2 # TODO: validate input /var/lib/dpkg/info/t-budget.postinst: #!/bin/sh # Source debconf library. . /usr/share/debconf/confmodule # generate config files...
