How To Upgrade Ubuntu 9.10 to Sabili 9.10

If you have an old version of Ubuntu, less than 9.10, you should first upgrade your system:

sudo aptitude update && sudo aptitude safe-upgrade

sudo aptitude dist-upgrade

Then, to convert Ubuntu to Sabily, follow these steps:

Open a terminal window (Applications→Accessories→Terminal), and execute the following command:

sudo wget http://www.sabily.org/sources.list.d/`lsb_release -cs`.list --output-document=/etc/apt/sources.list.d/sabily.list; sudo apt-get -q update; sudo apt-get --yes -q --allow-unauthenticated install sabily-keyring; sudo apt-get -q update

Then install the sabily package:

sudo aptitude install sabily



Answer ‘Yes’ when needed.
If you want to install the optional package WebStrict (Web Content Filtering tool), just run the following command:

sudo aptitude install webstrict

Finally, restart your computer to apply changes.
