Upgrading your server from Ubuntu 8.10 Intrepid Ibex to 9.04 Jaunty Jackalope

28 April 2009 175 views One Comment

Last week Ubuntu released Ubuntu 9.04 Jaunty Jackalope. This article will cover how to upgrade your server from Ubuntu 8.10 to Ubuntu 9.04.

1. Update your package list

# sudo aptitude update

2. Install the upgrade manager

# sudo aptitude install update-manager-core -y


3. Run the upgrade manager

# sudo do-release-upgrade

Ubuntu will now run through the upgrade process. It may ask you for input depending on your current setup. At the end of the upgrade the server will ask to reboot itself. Once the server has rebooted, the setup is complete. Now run:

cat /etc/lsb-release

to verify that the upgrade was successful and complete. The output should be something similar to:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.04
DISTRIB_CODENAME=jaunty
DISTRIB_DESCRIPTION=”Ubuntu 9.04″

Congratulations! Your server is now upgraded to Ubuntu 9.04. Enjoy!

    I had to reboot my server first before I could do do-release-upgrade. Kept complaining of a Fork Failure or an Error 12 being unable to allocate memory.
