Instalação do Arch Linux

Consegui configurar minha net adsl que usa modem usb. Digite o comando pacman -Syu para poder atualizar a lista de pacote, depois digitei pacman -S xorg, mas apareceu uma mensagem de erro dizendo que não existia o arquivo core em /etc/pacman.d/core. Novamente digitei pacman -Syu e de o mesmo. Fui na pasta /etc/pacman.d/ e verifiquei que só existia um arquivo chamado de mirrorlist cheio endereço de serve. O que eu devo fazer??? Desde já agradeço.
É viva ao Arch Linux

Verifique se há mais de um pacman.conf em seu /etc, como um pacman.conf e um pacman.conf.new.

o seu /etc/pacman.conf deixe assim:


#
# /etc/pacman.conf
#
# See the pacman manpage for option directives

#
# GENERAL OPTIONS
#
[options]
# The following paths are commented out with their default values listed.
# If you wish to use different paths, uncomment and update the paths.
#RootDir = /
#DBPath = /var/lib/pacman/
#CacheDir = /var/cache/pacman/pkg/
#LogFile = /var/log/pacman.log
HoldPkg = pacman glibc
#XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u

#
# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
#
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#

# Testing is disabled by default. To enable, uncomment the following
# two lines. You can add preferred servers immediately after the header,
# and they will be used before the default mirrors.
#[testing]
#Include = /etc/pacman.d/mirrorlist

[core]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist

[extra]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist

[community]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist

# Unstable is disabled by default. To enable, uncomment the following
# two lines. You can add preferred servers immediately after the header,
# and they will be used before the default mirrors.
#[unstable]
#Include = /etc/pacman.d/mirrorlist

# An example of a custom package repository. See the pacman manpage for
# tips on creating your own repositories.
#[custom]
Server = file:///home/custompkgs

[kdemod]
Server = http://kdemod.ath.cx/repo/current/i686

[archlinuxfr]

Server = http://repo.archlinux.fr/i686



o seu /etc/pacman.d/mirrotlist deixe assim:

fisso isso que vc falou deu tudo certo.
Digitei pacman Syu ai ela baixou uns 143 mb. Depois digitei pacman xorg e baxou uns 45 mb de arquivos. Reniciei o meu pc para ver mas informações no artigo de pos-instalação, mas quando voltei para o arch o meu modem não era mais detectado. Fui no resulinux e botei para procura o drive do meu modem que e cxacru na partição do arch e não achou nada, porem eu não sei se o driver ja estava instalado antes unica coisa que sei e que estava funcionando, tentei compilar o driver e nada.
