Source : apt-setup Version: 0.47 This bug still exists in the latest fix also. The patch in 0.47 version does add an entry in /etc/apt/sources.list., but the grub installation and selecting a "Standard system" install under tasksel fails with an error, "File not found " and "Failed to fetch cdrom" errors. Manually doing a "apt-get update" inside /target also didnt help.
