How To Upgrade From Ubuntu 14.04 To Ubuntu 14.10 Final Beta Or Ubuntu 14.10 RC

Hello Linux Geeksters. As you may know, Ubuntu 14.10 Utopic Unicorn is scheduled for release on the 23rd of October. While the final Beta has been already released, on the 25th of September, Ubuntu 14.10 RC will become available starting with the 16th of October, one week before the final version.

Despite the fact that Ubuntu 14.10 is not yet stable, it can used for daily tasks.

How To Upgrade From Ubuntu 14.04 To Ubuntu 14.10 Final Beta Or Ubuntu 14.10 RC

In this article I will show you how to upgrade from Ubuntu 14.04 Trusty Tahr to Ubuntu 14.10 Beta (under development).

Canonical provides a straight-forward upgrade path, so it is quite easy to get Ubuntu 14.10 beta. The below instructions work for Ubuntu 14.10 and all the flavors: Kubuntu, Xubuntu, Lubuntu, Ubuntu GNOME, even Ubuntu Mate, which is not an official flavor yet.

So, let’s start. The first thing you have to do is make sure that your system is up to date:

$ sudo apt-get update
$ sudo apt-get dist-upgrade

Next, you have to install the update-manager-core, if it is not already available and run the upgrade:

$ sudo apt-get install update-manager-core
$ sudo do-release-upgrade -d

Without any argument, the d-release-upgrade command looks for the latest stable version of Ubuntu available, but -d tells the upgrader to include the unstable versions also.
