How to upgrade to Cassandra

Upgrades vs Fresh Installs

We strongly recommend Fresh installs (downloading the CD and installing from it), the reasons being:

  • You get everything from a fresh install. You don't always from an upgrade (for instance you don't get all the artwork).
  • You don't loose your settings or data from a fresh install provided you've assigned /home a separate partition.
  • It's usually faster to do a Fresh Install and it saves bandwidth (Cassandra is about 2GB of data to download... with an upgrade you download 2GB, with a fresh install you download the same data compressed in a CD of 700MB)


Of course with a Fresh install you loose all your installed applications and system settings and you may not want to go through that again. For this reason we're publishing this howto. Remember though, this is a best effort, only recommended to people who are experienced with APT and who are not afraid to use the command line.


As with a Fresh install we recommend you backup your data before you proceed with the upgrade.


Note: If you're using a proprietary nVidia or ATI driver you may experience problems while upgrading xorg and the linux kernel. Unless you know what you're doing we strongly recommend you do a fresh install.


Good luck. Enjoy Cassandra.

From Bianca Stable to BETA012

Open a terminal and type the following commands:

sudo apt-get remove openoffice.org*
sudo gedit /etc/apt/sources.list


In /etc/apt/sources.list:

  • Change all occurrences of "edgy" to "feisty"
  • Change all occurences of "bianca" to "cassandra"
  • Save the file

Very Important: Repeat the three commands above until the output says for both upgrade and dist-upgrade that there is nothing to upgrade to.
