The Ubuntu team is pleased to announce the Release Candidate for Ubuntu 9.10 Desktop and Server editions, Ubuntu 9.10 Server for UEC and EC2, and the Ubuntu Netbook Remix. Codenamed “Karmic Koala”, 9.10 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.
We consider this release candidate to be complete, stable, and suitable for
testing by any user.
Ubuntu 9.10 Desktop Edition improves on the work of 9.04 to get you going faster, with improved startup times and a streamlined boot experience.
Ubuntu 9.10 Server Edition integrates Ubuntu Enterprise Cloud setup in the installer and provides improvements to system security with AppArmor, including an AppArmor profile for libvirtd to further isolate virtual machines from the host system.
Ubuntu 9.10 Server for UEC and EC2 brings the power and stability of the Ubuntu Server Edition to cloud computing, whether you’re using Amazon EC2 or your own Ubuntu Enterprise Cloud.
The Ubuntu 9.10 family of variants, Kubuntu, Xubuntu, Edubuntu, Ubuntu Studio, and Mythbuntu, also reach RC status today. This release sees the first technology preview of Kubuntu Netbook.
The final release of Ubuntu 9.10 is scheduled for 29 October 2009 and will be supported for 18 months on both desktops and servers. Users requiring a longer support lifetime on the server may choose to continue using Ubuntu 8.04 LTS, with security support until 2013, rather than upgrade to 9.10.
Before installing or upgrading to Ubuntu 9.10 please review the instructions and caveats in the release notes:
In addition, there are a small number of known bugs in the release candidate that will be fixed before the Ubuntu 9.10 release, but warrant highlighting for your attention:
