Drupal core tries to update to current version Many sites on my server are running Drupal 7.23, I usually use Drush to update them without any issue. Eveything works fine with modules and themes but Core keeps installing 7.23 on itself.

The admin/reports/updates page display this :



Drupal Core 7.23
  Recommended version: 7.23
  Security update: 7.24
  Last version: 7.25


It obviously tries to update to the recommended version, which is in this case the current one (7.23).

I use the permissions guidelines given in the script on the bottom of this page. I tried to change the file owner, it is not working. We recently installed Nginx as a reverse proxy on our server but the problem still the same calling directly Apache.

I also have some sites running Drupal 7.24 and no issue when updating to 7.25.

Any clue on the origin of this issue ?
I found the solution, with the following command line.

drush pm-update drupal-7.25


I still do not understand why the regular update fails but this last command works fine.
