Hello.
When using the debian12 dvd disc for installation, choose to use network
mirroring in the mirroring step, but at this time the system network is
disconnected and the installation cannot continue.
When using the dvd installation disk, it is to complete the installation
quickly, but also want to install the system and configure the mirror
station for subsequent use.
1. Is there a way not to select the network mirror site in the installation
wizard, and reconfigure the network mirror site through dpkg-reconfig xxx
and other methods after the system installation is complete.
2. The installation wizard selects the network mirror site, but the actual
installation process uses the software package in the DVD disc.
