General Upgrade Information

See also: Upgrading to 13.04 Raring Ringtail

An upgrade is the process of going from an earlier version of Ubuntu to a newer version of Ubuntu with an installed system. An example of this would be going from Ubuntu 11.10 to Ubuntu 12.04 LTS. To avoid damaging your running system, upgrading should only be done from one release to the next release (e.g. Ubuntu 12.04 to Ubuntu 12.10) or from one LTS release to the next (e.g. Ubuntu 10.04 LTS to Ubuntu 12.04 LTS). If you wish to 'skip' a version, you can backup your data and do a fresh installation, or progressively upgrade to each successive version. For example, to upgrade from Ubuntu 11.10 to Ubuntu 12.10, first upgrade to 12.04, then upgrade 12.04 to 12.10.

Renewing the Installation without formatting the partitions (in contrast to upgrading), will also keep the personal data and configurations under /home but will renew all system settings under /etc as well as the default set of installed packages.

You should always run a supported release of Ubuntu in order to receive security bug fixes. If you are using old hardware, you should not stick to obsolete and unsupported releases to keep your system fast; it is much better to install a lighter distro like Lubuntu.

The long time support (LTS) version is recommended for people in an environment (generally commercial/industrial) that do not want things to change and do not require newer/faster/updated versions, but instead want to keep the same version for a longer amount of time.

On this page you can see some arguments for an upgrade and for a fresh install.

An easy way to test a newer version of Ubuntu for compatibility with your machine is trying the Live CD before upgrading/renewing the installation.

To find your Ubuntu version, select the "cog" in the upper right corner of the top panel, then click:

  • About This Computer

or

lsb_release -a

IconsPage/warning.png Using packages from repositories not controlled by Ubuntu is not recommended as it can be a security risk and may break or complicate your upgrade. If you have used EasyUbuntu or Automatix (neither of which is recommended nor supported), you may have problems upgrading to a newer version and may require a fresh install. If you have installed software from other sources, the upgrade may go more smoothly if you remove this software before attempting the upgrade.

If you have trouble downloading only when doing a distribution upgrade, try viewing UpgradeProblems.

LTS stands for "Long Term Support," meaning the Desktop Edition is supported for three years, and the Server Edition is supported for five years. "Supported" means that Ubuntu will continue to provide security and the like until the EOL (End-of-life) date.
