To run the Debian base system configuration install time wizard again, you can use the following steps:
Boot the system into the Debian installation media. This can typically be done by inserting the installation media into the system and restarting the system.
Press the appropriate key to enter the boot menu, and then select the installation media from the menu.
Select "Install" from the menu to begin the installation process.
Follow the prompts to complete the installation process. When you reach the point where you are asked to configure the base system, select the option to run the configuration wizard.
Follow the prompts to complete the base system configuration process.
Keep in mind that running the base system configuration install time wizard again will overwrite any changes you have made to the system since the initial installation. It is important to make sure that you have backed up any important data or configuration files before running the wizard again.
Alternatively, you can manually configure the base system by editing the appropriate configuration files and using the appropriate commands. However, this can be a more complex and error-prone process, so it is generally recommended to use the install time wizard if possible.
