If you installed Kali offline from a CD/DVD or USB (or have chosen not to connect to internet during installation), you probably have an empty sources.list file with just 2 lines on it (CDROM’s). ... you won’t get the mirrors or repositories during a hard disk install added to your sources.list file. This will cause issues in the future when seeking new or updated software packages from the Kali repos.
