📝 NAME

dpkg-reconfigure - reconfigure an already installed package

📋 SYNOPSIS

dpkg-reconfigure [options] packages

📖 DESCRIPTION

dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a package or packages to reconfigure. It will ask configuration questions, much like when the package was first installed.

If you just want to see the current configuration of a package, see debconf-show(1) instead.

⚙️ OPTIONS

• -ftype, --frontend=type — 🔧 Select the frontend to use. The default frontend can be permanently changed by:

  dpkg-reconfigure debconf

  Note that if you normally have debconf set to use the noninteractive frontend, dpkg-reconfigure will use the dialog frontend instead, so you actually get to reconfigure the package.
• -pvalue, --priority=value — 🔽 Specify the minimum priority of question that will be displayed. dpkg-reconfigure normally shows low priority questions no matter what your default priority is. See debconf(7) for a list.
• --default-priority — Use whatever the default priority of question is, instead of forcing the priority to low.
• -u, --unseen-only — 👁️ By default, all questions are shown, even if they have already been answered. If this parameter is set though, only questions that have not yet been seen will be asked.
• --force — 💥 Force dpkg-reconfigure to reconfigure a package even if the package is in an inconsistent or broken state. Use with caution.
• --no-reload — ♻️ Prevent dpkg-reconfigure from reloading templates. Use with caution; this will prevent dpkg-reconfigure from repairing broken templates databases. However, it may be useful in constrained environments where rewriting the templates database is expensive.
• -h, --help — ❓ Display usage help.
