Before you start
ⓘ We recommend that you back up your existing Ubuntu installation before you update your computer.
Being able to upgrade Ubuntu from one version to the next is one of Ubuntu’s best features. You benefit from getting the latest software, including new security patches, and all the upgraded technology that comes with a new release without having to resort to reinstalling and reconfiguring your system.
Best of all, upgrading Ubuntu to the latest release is easy. As we’ll demonstrate!
If you are upgrading from Ubuntu 14.04, please read the upgrade notes for more information.
Launch the Software Updater
On versions of Ubuntu prior to 18.04, press the Superkey (Windows key) to launch the Dash and search for Update Manager.
For Ubuntu 18.04 or later, click on the Show Applications icon in the bottom left of the desktop and search for Update Manager.
As the application launches it will first check if there are any updates for your current version of Ubuntu that need to be installed. If it does find any, install these first and run Update Manager again if you need to restart your machine.
Check for updates
Update Manager will open a window to inform you that your computer is up to date. Click on the Settings button to open the main user-interface.
Select the tab called Updates, if not already selected. Then set the Notify me of a new Ubuntu version dropdown menu to either For any new version or For long-term support versions, if you’re wanting to update to the latest LTS release. You may be asked for your password to make this change. See the Ubuntu wiki for details on the differences between standard and LTS releases.
Click on Close to be taken back to the update pane and OK to close this.
We now need to open Update Manager one more time, only this time Update Manager will open up and tell you that a new distribution is available. Click Upgrade.
If no upgrade appears
An upgrade will not appear if upgrades to the next release of Ubuntu are not recommended yet and have not been enabled.
Install the upgrade
After asking for your password, you will be presented with the Release Notes for the release you’re about to upgrade to.
Select the Upgrade button to start the initialisation process. A few moments later you’ll be asked Do you want to start the upgrade? Press Start Upgrade to pass the point of no return and start the upgrade process.
The upgrade will now proceed. The Distribution Upgrade pane will track the upgrade process and allow you to monitor progress. As the process is dependent on both your network connection and the performance of your computer, the upgrade could take anything from ten or 20 minutes to an hour or more.
After the new packages are installed, you may be asked whether you want to remove any obsolete packages. These are packages that were installed on your previous version of Ubuntu but are no longer required by the new one. You can safely select Remove.
Finally, you’ll be asked to restart the system to complete the upgrade.
Congratulations! You have successfully upgraded Ubuntu!
If you get stuck, help is always at hand.
