WARNING / take a look here prior to upgrading and installing!

I'm posting this as a forum user and not as a staff member. This is all on your own risk. Please be careful.

There are two sections : section [i] is regarding to installing and section [ii] is regarding to upgrading.

section [i] : READ THIS PRIOR TO INSTALLING DAPPER :

Download the cd image here : http://www.ubuntu.com/download
You should probably download the desktop or alternate install cd.
Installation instructions are found here : https://wiki.ubuntu.com/Installation
You can find further burn instructions here : https://wiki.ubuntu.com/BurningIsoHowto
Burn the cd "as an image" on a 700 mb cd. Don't try to burn it on a 650 mb cd.

This problem may happen performing a fresh install with the Desktop CD and it seems that i'm not alone in this case : http://ubuntuforums.org/showthread.php?t=186309

section [ii] :READ THIS PRIOR TO UPGRADING TO DAPPER : :
https://wiki.ubuntu.com/DapperUpgrades

You should close all applications during upgrading to Dapper. If you don't your system might become unresponsive.

You should also disable screen savers/lock before upgrading. See here for someone who had troubles because of it :

You should remove docbook-utils before upgrading.
$sudo apt-get remove docbook-utils

During dist-upgrading from Breezy to Dapper non-official repos should be commented. Dist-upgrading using the update-manager tool is easy as it comments all non-official repo's automatically.

good luck!

Most of the times the update-manager works fine. I recommend this method of dist-upgrading to non-experienced users. Personally I prefer doing it "by hand" using the commandline.

If you need to dist-upgrade by hand. Here's some information. dist-upgrading by hand :

First backup your personal files if you haven't done so.

And backup your sources.list :
$sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

Change breezy to dapper and make sure to comment all non-official repositories.Or use this clean Dapper sources.list :

to edit your sources.list :
$sudo gedit /etc/apt/sources.list
Or from the terminal :
$sudo pico /etc/apt/sources.list

get into ctrl-alt-f1

$sudo apt-get update

It happens quite often that this command wants to remove ubuntu-desktop / kubuntu-desktop so don't worry.

$sudo apt-get dist-upgrade

Make sure everything is installed by :
$sudo apt-get install ubuntu-base
$sudo apt-get install ubuntu-desktop (or kubuntu-desktop / edubuntu-desktop / xubuntu-desktop)

Now do a reboot and you should be dist-upgraded from breezy to dapper.

Are you having problems ? Read this first :

If you have problems and you need help IMHO it's best to start a new thread. In your own new thread : be elaborate about your problems. Post the errors you get. Post your /var/log/Xorg.0.log and ~/xsession-errors log files. Post the result of $lspci and post your /etc/apt/sources.list.

edit :
I changed uncommented to commented. I hope it was obvious that in order to disable non official repo's those repo's have to be commented in the sources.list.
