# Desc: How to create a local repository for
# Ubuntu 9.10 Karmic Koala.
# -------------------------------------
# Setup the Server
# -------------------------------------
# Install Ubuntu (I used 9.10) on a machine with plenty of
# free storage space (I used an 8GB OS vmdk and an 80GB data
# vmdk used through LVM so that I could easily add/grow to
# it in the future if necessary).
# Create the mirror user, I'll be using ubuntu.
# NOTE: You don't have to add this user to the wheel but if you don't, the steps below that require sudo
# will require you to run them from an account with root or wheel access and may also require
# that you change the ownership/group of files/directories afterwards.
sudo useradd -m ubuntu -Gusers,wheel
sudo password ubuntu
# UPDATE 2012/01/30: As Dave points out below, you'll need to create your mirrorkeyring folder with the correct user account.
# If you aren't already running as that user, you can change your shell using su
su - ubuntu
# Update your apt-get package listing
sudo apt-get update
# Install debmirror
sudo apt-get install debmirror
# Create the location for the repo data to live
sudo mkdir -P /mirror/ubuntu
# Set the permissions for the repo data
sudo chown -R ubuntu:ubuntu /mirror/ubuntu
sudo chmod -R 771 /mirror/ubuntu
# Setup the keyring for correctly verifying Release signatures
gpg --no-default-keyring --keyring /home/ubuntu/mirrorkeyring/trustedkeys.gpg --import /usr/share/keyrings/ubuntu-archive-keyring.gpg
# Create the mirrorbuild.sh script
vim /home/ubuntu/mirrorbuild.sh
# NOTE: The ubuntu community documentation has you using
# the HTTP protocol for the mirror build script
# however, I prefer rsync because we can rate limit.
# When the download is going to take days,
# I'd like to be able to use my connection in
# the interim.

# BEGIN MIRRORBUILD.SH SCRIPT

# Don't touch the user's keyring, have our own instead

export GNUPGHOME=/home/ubuntu/mirrorkeyring
# Arch= -a # Architecture.
# For Ubuntu can be i386, amd64, powerpc and/or sparc (sparc support begins with dapper)
#
# Comma separated values
arch=i386,amd64
# Minimum Ubuntu system requires main, restricted
# Section= -s # Section
# (One of the following - main/restricted/universe/multiverse).

# Server= -h # Server name,
# minus the protocol and the path at the end
# CHANGE "*" to equal the mirror you want to create your
# mirror from. au. in Australia ca. in Canada. This can be
# found in your own /etc/apt/sources.list file,
# assuming you have Ubuntu installed.

# Dir= -r # Path from the main server,
# so http://my.web.server/$dir, Server dependant

# Proto= -e # Protocol to use for transfer
# (http, ftp, hftp, rsync)
# Choose one - http is most usual the service, and the
# service must be availabee on the server you point at.
# NOTE: debmirror uses -aIL --partial by default.
# However, if you provide the --rsync-options
# paramter (which we do) then you HAVE to provide
# it -aIL --partial in addition to whatever You
# want to add (e.g. --bwlimit) If you don't
# debmirror will exit with thousands of files
# missing.

# Outpath= # Directory to store the mirror in
# Make this a full path to where you want to mirror the material.
#
outPath=/mirror/ubuntu/
# The --nosource option only downloads debs and not deb-src's
# The --progress option shows files as they are downloaded
# --source \ in the place of --no-source \ if you want sources also.
# --nocleanup Do not clean up the local mirror after mirroring
# is complete. Use this option to keep older repository
# Start script

# Add execute permissions on the mirrorbuild.sh script

# Setup the mirror
# --------------------------------------
# Install apache2
sudo apt-get install apache2

# Updating the Repo Mirror
# -------------------------------------
# To update the repo mirror, just execute the mirrorbuild.sh

# Configure Clients to Use this Repo
# -------------------------------------
# Update the apt sources list
cd /etc/apt
