How do I upgrade Drupal Core?

The Drupal One-Click application comes with Drush, a command line tool for administering Drupal., pre-installed. It allows you to upgrade Drupal easily.

First change into the directory containing Drupal:

cd /var/www/html/drupal/

To check for an available update run:

drush pm-update -n

And to update to the new release, run:

drush pm-update drupal-7.34

Same here. Any solution?

Just to update. Some might get this error.

Command pm-update needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to run this command.                                              [error]
