Upgrading Xubuntu

Upgrading Xubuntu

New regular releases of Xubuntu are released every 6 months and Long Term Support (LTS) releases every 2 years. Currently, regular releases are supported for 9 months and LTS releases for 3 years.

The Software Updater will inform you when a new version for your upgrade path is available for download. To change the upgrade path, see Changing your upgrade path.

Upgrades usually take a while to complete. Typically, around 1000 MB of packages must be downloaded and installed, although the actual figure depends on how many packages are already installed on your computer.

Upgrading to the next available release

Go to → Settings Manager → Software Updater and wait for the list of available updates to be downloaded
If a new version of Xubuntu is available, a box at the top of the window will appear saying that a new distribution release is available
To upgrade to the next available release, save all of your open documents and click the Upgrade button in → Settings Manager → Software Updater


	If you are not getting an upgrade notification, or aren't seeing the release you are expecting to upgrade to, see Changing your upgrade path.

Changing your upgrade path

There are two main upgrade paths you can follow: either upgrade to long-term support (LTS) releases only, or upgrade to all releases.

If you decide to follow the LTS upgrade path, you will be notified of new releases every two years. If you decide to follow the regular releases upgrade path, you will be notified of new releases every 6 months. You can change from regular to LTS upgrade path once you have reached the next LTS release.

If you want to change your upgrade path, you can do it when running an LTS version. To do so, choose one of the following options:

Navigate to → Software → Software & Updates and select the Updates tab. In the Updates tab, select either For any new version or For long-term support versions from the Notify me of a new Ubuntu version dropdown menu depending on your choice.
Open the → Accessories → Terminal Emulator and run sudo edit /etc/update-manager/release-upgrades and change the line starting with prompt= to prompt=normal (for all releases) or prompt=lts (for LTS releases) depending on your choice


	If you are running a regular release that is not immediately followed by an LTS release, you should not change the upgrade target to long-term support (LTS) releases only.


	Upgrading an LTS version to anything other than another LTS version will lose the long term support.

Upgrading to the development version


	Development releases often suffer from package breakages and other problems. Only install a development release if you are prepared to attempt to fix these problems for yourself or if you want to help the Xubuntu team by testing and giving feedback.


	You will need to be running the latest regular version to be able to upgrade to the version currently under development.

If you would like to install and test the latest development version of Xubuntu before it is released, run update-manager -c -d at the command line. This will allow you to upgrade to the current development release. Please consider getting involved with reporting usage of development versions and associated packages.

Notifications of new Xubuntu versions

This section of the Software Updater deals with the way you wish future versions to be given to you. You have three options:

For any new version - You will get notifications of all new releases, once in 6 months.
For long-term support versions - You will get notifications of new Long-term Support (LTS) releases, once in 2 years.
Never - You will not get notifications of new releases.


	Opting in for Long-term Support (LTS) notifications is usually the recommended option, especially if you are running Xubuntu on a production machine and/or need maximum stability.


	It is not recommended to user the Never setting. Unless you remember to manually upgrade often enough, this will leave you with an unsupported system. Additionally, you will be missing out on bug fixes, updates for potential security problems and hardware support improvements.
