Estou tentando inicializar o PXE e reconstruir completamente um novo servidor com uma imagem "Ubuntu 12.04 Server" na rede usando o apt-mirror, mas recebo vários erros no meio da instalação. Eu sou capaz de reconstruir com sucesso o mesmo servidor com um CDROM físico (criado usando os mesmos arquivos da imagem "ubuntu-12.04.2-server-amd64.iso") sem problema, ainda tenho problemas de construção através da rede, uma vez que fornece as seguintes mensagens de erro logo depois de particionar os discos e iniciar a última grande transferência de arquivos. Como resultado, não consegui criar um servidor PXE de sucesso usando a rede interna da minha empresa (usando o repositório externo).
Erro 1:
!! Instale o sistema básico
Aviso do Debootstrap
Aviso: não foi possível baixar a ejeção de pacote (ver 2.1.5 + deb1 + cvs20081104-9 arc amd64)
Erro 2:
!! Instale o sistema básico
Aviso do Debootstrap
Aviso: não foi possível baixar o pacote liblzma5 (ver 5.1.1alpha + 20110809-3 arc amd64)
Erro 3:

Implementei pela primeira vez uma solução DHCP / TFTP usando o pxelinux ( link ), mas depois mudei para o gpxelinux com o syslinux para tentar para que isso funcione (além disso, parece que o uso de HTTP é mais rápido que o TFTP etc.). Ainda sem sucesso, tentei usar um arquivo Kickstart simples:
install
url --url http://10.16.25.80:4040/ubuntu/repository/
... juntamente com um repositório apt-mirror completo (como sugerido aqui - & gt; Não é possível instalar o 12.10 com o PXE ) sem melhorias. Eu também tentei usar a imagem "ubuntu-12.04.2-alternate-amd64.iso" também.
O servidor de hospedagem é de hardware similar e foi previamente configurado com o Ubuntu Server 12.04 (preciso) com o servidor Chef 10.18.2 usando o web-ui que usa o merb para serviços web (HTTP). Este servidor atua como o host DHCP / HTTP / TFTP / APT-MIRROR.
