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 8.8.8.8, 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)
