(had problems with proxy setting before, tho i can't remember what) ### Mirror settings # If you select ftp, the mirror/country string does not need to be set. #d-i mirror/protocol string ftp d-i mirror/country string manual d-i mirror/http/hostname string 192.168.1.74:3142 d-i mirror/http/directory string /ftp.uk.debian.org/debian #d-i mirror/http/proxy
ofc this leaves the proxy in /etc/apt/sources.list after install but i didn't have a problem with that you could just sed it out or something in the late_command
