debconf-show — query the debconf database
debconf-show packagename [...] [--db=dbname] debconf-show --listowners [--db=dbname] debconf-show --listdbs
debconf-show lets you query the debconf database in different ways.
The most common use is "debconf-show packagename", which displays all items in the debconf database owned by a given package, and their current values. Questions that have been asked already are prefixed with an '*'.
This can be useful as a debugging aid, and especially handy in bug reports involving a package's use of debconf.
Specify the database to query. By default, debconf-show queries the main database.
Lists all owners of questions in the database. Generally an owner is equivalent to a debian package name.
Lists all available databases.
