Ubuntu 15.04 Vivid Vervet is the upcoming latest version of Ubuntu. The stable version of Ubuntu 15.04 has not been released yet. According to the Ubuntu 15.04 release calendar, it is supposed to be release in the month of April 2015. If you want to test this OS you can download and install beta 2 (unstable release) with the help of external media. Ubuntu 15.04 Beta 2 ISO file is available for download on the official site of Ubuntu.
If you have Ubuntu 14.10 installed, then you can upgrade it to Ubuntu 15.04 Vivid Vervet easily. Ubuntu 15.04 is still in beta phase so I would recommend you to wait a little and enjoy the full stable release. But if you still want to test the OS follow the steps below. The same procedure will work for the installation of final stable release.

  • Open Software Updates from Unity dash. In Settings click on Updates tab. In the open window set “Notify me of a new Ubuntu version” as “For any new version”. Check the “pre release updates” under “Install updates from”, if want to get any pre releases updates.
