To upgrade or install Joomla, follow the steps below:

Step 1: Upgrading Joomla CMS via Live Update

If you have an existing Joomla website, then step 1 is all you need. but before upgrading, make sure to back up your site. That’s very important.

There are many components available to help you backup  your site.

The recommended way to update installations of Joomla! is to use the Joomla Updater component found in the Components menu of your site Administrator.

Depending on your site settings, if an update is available there will be a message indicating this and a button to press to Upgrade Now. Which update you’ll see depends on the setting for Update Server and caching.

After logging on to the admin backend, the Update Now button should be available as shown in the image below. Click the button to be taken to the Live Update page.

Joomla Upgrade Ubuntu

On the Live Update page, if everything is good and backup has been taken, click the Install the Update button to begin. The first option shows the latest update of the major release in use. The second option shows the latest update of the latest major.

The “Default” update channel will show you notifications for all updates of the current Joomla release (3.x)

If everything is right, your site should successfully update to the latest version.

Ubuntu Joomla update

That’s how to upgrade Joomla CMS via its Live update feature.

If you’re upgrading from one major version to another, for example. upgrading from 3.x to 4.x, you will need to update Joomla’s Update Channel. You can configure where Joomla! gets its update information from:

  • Update Channel: (Default/Joomla Next/Testing/Custom URL) This allows you to choose the update source for Joomla.
    • Default: is the recommended setting to stay on the latest release. This ensures that you still receive all released updates.
    • Joomla Next: switch from one major release to next major release (Joomla 3.x to Joomla 4).
    • Testing: is used for testing Joomla! releases prior to their release as ‘Stable’. With this setting nightly builds will be shown until a Beta or RC (Release Candidate) is available. It is recommended not to use on Production sites. Only use this setting on test sites.
    • Custom URL: This setting allows a custom update server to be used. It is recommended not to use on Production sites. Only use this setting on test sites.
  • Custom URL: This field is used to point to a custom XML update source URL, used only when the ‘Update Server’ option is set to ‘Custom URL’.
