This is just my note about upgrading (reinstall) my Ubuntu from Karmic to Lucid.

Before installing Lucid :

Backup pidgin logs located in ~/.purple/logs

mkdir ~/backup_pidgin
cp -dfr ~/.purple/logs ~/backup_pidgin

After your Lucid successfully installed, then think what packages you should remove and what packages you should install. In my opinion, default games in Ubuntu is not important, so I remove it all. Then I don’t like these packages :

1. brasero. I don’t need to burning DVD.
2. transmission-common. This package used for sharing file thru torrent service. I need package like this, but I choose vuze.
3. f-spot. I like digiKam.
4. empathy. I like pidgin.
5. gwibber. I don’t need this social microblog package.

sudo apt-get purge -y --force-yes brasero transmission-common aisleriot quadrapassel gnomine gnome-sudoku gnome-mahjongg gnome-games-common gbrainy f-spot empathy

Something missing?

Think what you need… Multimedia? Programming? Graphic? Internet?
Add these repositories into your Lucid :

sudo add-apt-repository ppa:team-xbmc
sudo add-apt-repository ppa:pidgin-developers/ppa
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

And Add this line to your /etc/apt/sources.list

deb http://packages.medibuntu.org/ lucid free non-free

Before installing it all, let’s upgrade our system :

sudo apt-get update
sudo apt-get upgrade -y --force-yes
sudo apt-get dist-upgrade -y --force-yes

So now, let’s start from multimedia task. If you want to watching HD video, XBMC is what you need. XBMC not only video player, but also audio player and photo viewer. I also love VLC for watching small video eace:, audacious for listening music, and cheese for webcam. lives is for video editing.

sudo apt-get install -y --force-yes ubuntu-restricted-extras
sudo apt-get install -y --force-yes xbmc xbmc-standalone vlc audacious cheese lives

In Graphic section, I need inkscape for draw vector image, gimp for photo editing, dia for draw diagram, and digiKam for manage my photo collection.

sudo apt-get install -y --force-yes inkscape gimp dia digikam

Internet
Filezilla is for FTP transfer, vuze for torrent transfer, pidgin for chat. Google Earth for your holiday eace:

sudo apt-get install -y --force-yes filezilla keepassx vuze pidgin googleearth

Programming?
Geany is my lovely text exitor. Qt Creator is IDE to build Qt application. Qgis is an open source geographic information system software.

sudo apt-get install -y --force-yes geany qtcreator qgis

Any other?
Stellarium is a planetarium in your desktop. Tilda is terminal but we can hide and show it by pressing F1 key. Install Virtualbox if you want to install another operating system inside your machine. Shutter is advanced screen capture program. Blueman manage your bluetooth. CCSM to manage your desktop effect, Gparted is partition manager in linux.

sudo apt-get install -y --force-yes stellarium tilda tomboy keepassx virtualbox-ose shutter wine blueman compizconfig-settings-manager gparted

Any?Absolutely YES!

cp -dfr ~/backup_pidgin ~/.purple/logs
