I want to customize a Ubuntu Desktop Iso and I have come that far, that I am in the chroot environment.
The problem is that I do not have Internet access in there to install anything.
I just can ping 126.96.36.199, but not www.google.com (for example). Everything goes through a proxy tho, so I made a file apt.conf in the apt folder of the chroot environment but still nothing happens.
I can not run lines like: sudo apt-get update -> It just says "W: Failed to Fetch over and over again"
Does somebody know a solution? I followed these steps (to the part with the sed commands)
