DO IT YOURSELF

The Web Installer is the easiest way to install Nextcloud on a web space. It checks the dependencies, downloads Nextcloud from the official server, unpacks it with the right permissions and the right user account. Finally, you will be redirected to the Nextcloud installer.

Right-click here and save the file to your computer
Upload setup-nextcloud.php to your web space
Point your web browser to setup-nextcloud.php on your webspace
Follow the instructions and configure Nextcloud
Login to your newly created Nextcloud instance!
You can find further instructions in the Nextcloud Admin Manual.

Note that the installer uses the same Nextcloud version as available for the built in updater in Nextcloud. After a major release it can take up to a month before it becomes available through the web installer and the updater. This is done to spread the deployment of new major releases out over time.
