Bug#608201: Install with network solve the problem.
I'm sorry but I'm doing tests and everything leads me to the script 01setup.
When I got it to work the apt-cdrom add, was omitted returning to format the target partition and do the installation again.
When I tried to edit from the beginning the library.sh the problem has persisted.
Now I have changed since the beginning, the line of 01setup:
sed 's/^/# /' < $ROOT/etc/apt/sources.list | sed 's/^# # */# /' > $file
cp $ROOT/etc/apt/sources.list > $file
And everything goes right, I say now from the beginning.
I think that file, it acts at the wrong time.
