A new version of Ubuntu OS is released every six months and this means that people who use the Linux operating system need to upgrade every now and then. However, the process is made easy as the upgrade makes use of the Advanced Packaging Tool, popularly known as APT to carry out the upgrade. This is a package that is uniquely designed for use with computers operating on the Linux system. The purpose of this article is not to discuss about the APT, but to show users how they easily and painlessly upgrade their versions to Ubuntu 10.10 version or other later versions like the Ubuntu 12.10 Quantal Quetzal. The steps are described in the paragraphs below.

Step one – Settings Configuration

Any machine that is running using an earlier version than Ubuntu 10.10 will not be able to directly upgrade to the latest Ubuntu 12.10 Quantal Quetzal version until the settings are configured. This is done by selecting the Settings tab in the Update Manager and then selecting Normal Releases at the Release Upgrade menu. There is no trouble with using the older versions as they are able to download security updates but the user who wants to enjoy the latest Ubuntu Desktop feel must get the upgrade. Once this is done, proceed to the section that allows one to see the available updates and there will be a notification on the availability of the latest Ubuntu version for upgrade. The process is started by clicking on the Upgrade button and one does not have to go to the trouble of installing the other available updates as the Linux system will automatically add them.

Step two – The Process

The moment one clicks the Upgrade button on the Update Manager, the system will show the release notes pertaining to the latest version about to be installed and these are to be read as many people skip them. At the end of the notes, there will be a question to confirm if one is sure of the upgrade to Ubuntu 12.10 Quantal Quetzal and if one wants to continue with the process, they should click the Update button.

Once the button is clicked, the installer will begin looking for packages that need to be installed by making use of APT. Once the packages have been identified, the installer will prompt one to begin by clicking the Start Upgrade button. Once the button is clicked, the upgrade will start and there will be a bar showing the progress. How fast the process should take will be dependent on the speed of the internet connection and your computer specifications.

Step Three – Completion

Once the Ubuntu 12.10 Quantal Quentzal has been fully downloaded and installed, the installer will prompt you to reboot the computer to complete the process. The reboot does not take any longer than normal and once done, the new Ubuntu desktop will be ready for use. The settings and programs that were in the previous version will remain unchanged but the Ubuntu desktop will have to be customized. Once done, Your Ubuntu Linux upgrade is complete.

    Or one can run “sudo do-release-upgrade -d”

      This command I have found works reliably if going from 12.x to later releases, but may not work with older versions like 10.x or 11.x to 12.x Ubuntu, I have seen many problems but yeah if you are doing a point release on the same core version then sudo do-release-upgrade -d is the obvious choice.

    ? “settings and programs that were in the previous version will remain unchanged”? is this true? Everything I’ve read at the Ubuntu forums says an update will erase your settings and programs. How do I verify this authors claim?

      I haven’t done the upgrade myself, but in checking 2 articles: http://askubuntu.com/questions/34605/how-does-the-ubuntu-upgrade-process-work and https://sites.google.com/site/easylinuxtipsproject/faq both would indicate that upgrades will keep former installs intact though they may not work if libraries that are used were upgraded and program isn’t updated or has trouble with it.
