GENERAL UPGRADE INFORMATION

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 17.10 to Ubuntu 18.04 LTS. To avoid damaging your running system,
upgrading should only be done from one release to the next release (e.g. Ubuntu
16.04 to Ubuntu 16.10) or from one LTS release to the next (e.g. Ubuntu 16.04
LTS to Ubuntu 18.04 LTS). If you wish to 'skip' a version, you can back up your
data and do a fresh installation, or progressively upgrade to each successive
version. For example, to upgrade from Ubuntu 16.10 to Ubuntu 17.10, first
upgrade to 17.04, then upgrade 17.04 to 17.10.

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

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.




CURRENT AND SUPPORTED VERSIONS

Supported versions of Ubuntu have finished their testing and are reliable and
recommended for everyday normal use. This is what you would usually have
installed on your machine. A generic upgrade guide can be found here, this guide
does not mention specific quirks per release. Refer to their own upgrade notes
as mentioned below.




FROM 16.04 LTS (OR 17.10) TO 18.04 LTS

 * Version: 18.04 (Bionic Beaver)

 * See the BionicUpgrades page for upgrading information




FROM 19.04 TO 19.10

 * Version: 19.10 (Eoan Ermine)

 * See the EoanUpgrades page for upgrading information

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.




UNSUPPORTED AND OBSOLETE VERSIONS

End-of-life releases are versions of Ubuntu that are obsolete and have no
official support. It would be best for users of these versions to perform a
fresh install of the latest Ubuntu release. However, users still trying to do an
upgrade can find instructions in this guide and may find suggestions at this
page.
