Bug#690350: d-i: Offline installation only with CD-ROM failed
If I decide not to use any network mirrors for packages, but only
the CD-ROM, then I cannot install grub or lilo. The problem is:
After I decided not to use network mirrors (and also no security
mirror) then the line for CD-ROM in /etc/apt/sources.list is not
activated! So the installer cannot install the packages of grub2
or lilo because apt cannot find packages on the CD-ROM.
Please activate the CD-ROM line in /etc/apt/sources.list,
if no network mirror were selected.
Have a nice day.
