Earlier, we reviewed the new features of Ubuntu 11.10 Oneiric Ocelot. Today the Ubuntu 11.10 Beta 2 was launched and now you can update your existing Ubuntu 11.04 operating system to the new and improved Ubuntu 11.10. In this post we will provide you with a complete walkthrough of the upgrade process to update Ubuntu Natty Narwhal to Oneiric Ocelot.
Note: It is advised to backup your system before performing the upgrade, since this is a Beta version and may have some functionality issues. Moreover, some new packages will be installed, existing packages will be upgraded and obsolete packages will be removed. This may result in the removal of some of your favorite applications.
To start the upgrading process, Press ALT+F2, type update-manager –d and click Run.
This will open the Update Manager where an upgrade button will be visible with a message that the new Ubuntu release is available for upgrade. Click Upgrade to continue
Shortly after continuing, you will be asked to enter your password, after which the upgrade process will initiate. During the process, the unsupported packages will have to be removed. For that, a prompt will appear with a list of the packages that will be removed, installed and upgraded. Click Start Upgrade to continue.
The update can take a long period of time and the new packages may require a few hours to download (depending upon your internet connection speed).
After the upgrade is complete, you will be prompted to restart your computer for the changes to take effect. Once you log back in again the GUI changes should be enough to inform you that the upgrade was successful, however, if you would like to confirm your existing Ubuntu version, type the following in the Terminal:
