Upgrading

There are several ways to upgrade from one Ubuntu release to another. This section gives an overview of the recommended upgrade method.

do-release-upgrade

The recommended way to upgrade a Server Edition installation is to use the do-release-upgrade utility. Part of the update-manager-core package, it does not have any graphical dependencies and is installed by default.

Debian based systems can also be upgraded by using apt-get dist-upgrade. However, using do-release-upgrade is recommended because it has the ability to handle system configuration changes sometimes needed between releases.

To upgrade to a newer release, from a terminal prompt enter:

do-release-upgrade

It is also possible to use do-release-upgrade to upgrade to a development version of Ubuntu. To accomplish this use the -d switch:

do-release-upgrade -d

Upgrading to a development release is not recommended for production environments.
