Nextcloud updates can be typically performed over the graphical administration interface.
In most cases updates are running very smooth but in other cases, some issues can occurred with the nextcloud remote download servers or the PHP-Backend or because something is running in a timeout. The update experience over the command line interface is much reliable and faster. Just try it out.
Go to your Nextcloud instance updater-directory, where the updater.phar file is located.
cd /var/www/nextcloud/updater
Run the updater with your webserver user, typically it’s www-data:
sudo -u www-data php updater.phar
The updater will prompt you approximately 3 times for your input:
Nextcloud Updater - version: v18.0.6-11-g50bdca3 dirty
Current version is 19.0.3.
