I have further tried to debug and added below code in wp-config but i am not getting any errors on the page neither in the path /wp-content/debug.log file is there.

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );

Dear users, please use manual update if you can't update automatically.

See here:

Updating WordPress

You can do it with cpanel:

1. Simple copy wp-content & wp-config.php to a directory out of public_html (for example, create a folder by name “backupold” and put files in it)
2. Download latest version https://wordpress.org/latest.tar.gz
3. Upload it in your wordpress directory (output file will be in public_html/wordpress for example)
4. Copy (backuped contents) “wp-content” folder & “wp-config.php” file to “wordpress” folder & replace
5. Move all files and folders from “wordpress” folder to your site directory (by default, public_html) & replace.

Now enjoy!
