Project drupal was updated successfully. Installed version is now 7.26.


I am on a vps using CentOS 6.5
Drush version 5.9
Currently installed version of Drupal is 7.23
I've had a similar problem in the past.  It looks like there's already a /home/sites/lg/public_html/drupal-7.26 (at least based on your post).  Make sure you have read / write access to it.  Better yet, run drush as root or under sudo.
