The beta release of Karmic Koala, the next version of Ubuntu Linux, just arrived on the net. Wondering what's new inside the open-source operating system?

Try it by yourself .. :o)

Upgrading from Ubuntu 9.04

 Open shell type

sudo apt-get dist-upgrade

To upgrade from Ubuntu 9.04 on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '9.10' is available. Click Upgrade and follow the on-screen instructions.
