Upgrade Ubuntu 14.10 to Ubuntu 15.04 (Vivid Vervet) Final Beta

Sponsored Link
The Ubuntu team is pleased to announce the final beta release of Ubuntu 15.04 Desktop, Server, Cloud, and Core products.

Codenamed "Vivid Vervet", 15.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs.

This beta release includes images from not only the Ubuntu Desktop, Server, Cloud, and Core products, but also the Kubuntu, Lubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu Studio and Xubuntu flavours. In addition to the usual suspects, we’re also welcoming a new flavour to the family this cycle with Ubuntu MATE.

The beta images are known to be reasonably free of showstopper CD build or installer bugs, while representing a very recent snapshot of 15.04 that should be representative of the features intended to ship with the final release expected on April 23rd, 2015.

There are, however, two bugs in this beta serious enough that it’s worth calling them out in the release announcement. Both bugs affect all flavours, are considered high priority, and will be addressed in upcoming daily builds:

After installation is complete, clicking the "reboot now" button will eject your installation medium but then fail to reboot. The simple workaround for this is to manually turn off or reset your computer and then boot into the freshly installed system.
When doing an OEM installation, the OEM user will not be removed at the end of the prepare-to-ship phase. Because of this, it is not recommended that oem-config be used with this beta, except for testing purposes.
