What command is used to reset keyboard configuration on Debian?

The command used to reset keyboard configuration on Debian is dpkg-reconfigure-keyboard-configuration. This command invokes the Debian package management system to reconfigure the keyboard settings that were established during the operating system's initial setup. It allows users to select the appropriate keyboard model, layout, and other settings through a straightforward text-based user interface.

By using this command, Debian ensures that the keyboard configuration aligns with the user's current requirements, potentially addressing issues that may arise from hardware changes or incorrect settings configured initially. This command is specifically designed for this purpose within the Debian family of operating systems, emphasizing its significance in managing system hardware preferences effectively. The other options do not represent valid or recognized commands for this specific task, as they either do not exist within the Debian system or are not intended for keyboard configuration adjustments.
