As of today (July 23, 2015), Ubuntu 14.10 has reached its End Of life and is no longer supported. No more package updates will be accepted to 14.10, and it will be archived to old-releases. The original End of Life warning follows, with upgrade instructions: Ubuntu announced its 14.10 (Utopic Unicorn) release almost 9 months ago, on October 23, 2014. As a non-LTS release, 14.10 has a 9-month support cycle and, as such, the support period is now nearing its end and Ubuntu 14.
The ISO Image files for Kubuntu Plasma 5 for Ubuntu 14.10 (Utopic Unicorn) daily build is now available for download. Plasma 5.0 introduces a new major version of KDE’s workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices.
