This is probably the first time I’m trying to upgrade WordPress using the automatic upgrade option available in the WordPress Admin Dashboard. And doing so showed this error message:
Downloading update from http://wordpress.org/wordpress-2.8.6.zip.
Download failed.: Could not create Temporary file
Installation Failed
Searching the Web lead me to the following thread at WordPress Forums:
WordPress › Support » Download failed.: Could not create Temporary file
What did actually work was setting the permissions (CHMOD) for wp-content folder to 777, using the FTP client (FileZilla) I use. Once WordPress was upgraded successfully, I changed the permissions back to 755.
This issue seems to occur only in Apache servers where Safe_Mode is On. You can read about that at Download failed – Could not create Temporary file | shantopagla.
