I am trying to automate an Ubuntu (12.04.1 64-bit) installation using Ubiquity and preseed on a desktop live CD. It almost works fine. I edited the txt.cfg and added
label unattended
menu label ^Unattended installation
kernel /casper/vmlinuz
append file=/cdrom/preseed/custom.seed boot=casper initrd=/casper/initrd.lz quiet splash noprompt --
The problem is that the installer shows the keyboard layout chooser and I have to click next. the correct language and keyboard layout (German) are already preselected.
What am I missing, or what's wrong in my custom.seed file, to automate the next click?
