Preseed and local mirror / apt-proxy

[Lebowski1]

Hi,

im trying to install ubuntu using pxe an preseed, but i run in some problems while using approx as apt-proxy.

At first, preseed and apt-roxy worked for lucid. Approx is working also fine under 12.04, only in connection with preseed i got this problem.

Now i'm using



d-i mirror/country string manual
d-i mirror/http/countries string manual
d-i mirror/http/hostname string 10.0.2.101:9999 # aproy
d-i mirror/http/mirror string 10.0.2.101:9999 # approx
d-i mirror/http/directory string /ubuntu/
d-i mirror/suite string precise
d-i mirror/http/proxy string
in my preseed-file.

After installation i used 'debconf-get-selections --install' to find the used values. So i could see, that


d-i mirror/http/mirror
ist overwritten with


d-i mirror/http/mirror gb.archive.ubuntu.com
How can i fix this?
