I am trying to upgrade Drupal from 7.14 to 7.18 using drush up
command.
Nothing gets updated and I see a bunch of failed warnings:
Failed to check available update data for CCK.
Failed to check available update data for CKEditor.
...
Failed to get available update data for 51 projects.
I can however download modules using drush dl module_name
All commands are run as root.
drush up -d
(-d is for debug)?
