Pacman error

Question

Hello
I have just installed Arch 2007.08-2 and everything went well (dual booting with Ubuntu), however when I try to add packages with pacman I get "error: failed to add target '.........' (could not find or read file.  Here is my pacman.conf:
# /etc/pacman.conf
# See the pacman manpage for option directives
# GENERAL OPTIONS
[options]
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
#[testing]
#Include = /etc/pacman.d/testing
[core]
# Add your preferred servers here, they will be used first
Server = ftp://ftp.heanet.ie/mirrors/ftp.archlin … re/os/i686
Include = /etc/pacman.d/core
[extra]
# Add your preferred servers here, they will be used first
Server = ftp://ftp.heanet.ie/mirrors/ftp.archlin … ra/os/i686
Include = /etc/pacman.d/extra
[community]
# Add your preferred servers here, they will be used first
Server = ftp://ftp.heanet.ie/mirrors/ftp.archlin … ty/os/i686
Include = /etc/pacman.d/community
#[unstable]
# Add your preferred servers here, they will be used first
#Include = /etc/pacman.d/unstable
# An example of a custom package repository.  See the pacman manpage for
# tips on creating your own repositories.
#[custom]
#Server = file:///home/custompkgs
It looks ok as far as I can determine.  I also have uncommented the server in /etc/pacman.d/core, community and extra.
The first thing I did after installiation was to pacman -Sy, then pacman -Su everything appeared to go as it should have so the internet connection is fine.
Am I missing something simple, I have read through the Wiki and went back through the forums several months.
Please help,  Thank you in advance

Answer 1

with the risk of sounding dull
I refer you to the man page as well as the wiki page
for the -U command.
also these two wiki pages may come in handy in understanding when you might need -U
Wiki.Arch / Makepkg
Wiki.Arch / ABS
hope you will have a pleasant experience of arch!
