Automatic Update (In-Panel): If the software supports automatic updates, log into the admin panel under “Updates,” check for a new version, and click “Update.” The system will fetch new files and run any database migrations as needed. Manual Update: Download the latest version (zip or tar.gz) from the official source. Upload the package to your server (e.g., /tmp) and extract it over the existing application directory: ```bash tar xzf new_version.tar.gz -C /var/www/html/ --strip-components=1 ``` If the application uses PHP Composer (Laravel, Symfony, etc.): ```bash cd /var/www/html composer install --no-dev --optimize-autoloader ``` If it’s Node-based (React, Vue, Angular, NestJS): ```bash npm install npm run build ``` Check permissions (chown -R www-data:www-data /var/www/html) and restart your web server (Apache/Nginx, PHP-FPM).
