A network error occurred:
Error NSURLErrorDomain -1005(-1005).
Make sure you can connect to the internet.
Background of an error -1005:
It is a URL loading error when a client computer's resource area fails establishing a handshake to access the data specified by a destination HTTP server-- for instance, when downloading Apple software updates.
This resource area conforms to 5 categories such as URL loading, cache management, authentication and credentials, cookie storage, and protocol support. The first category (URL loading) is consisted of 6 sessions and a session fails for some reason.
Now, secured the Root Certificate Authority system interacts with Safari, Mail, iChat and other Apple products which authorities are made available through the Software Update mechanism. You can view a part of the services on the X509Anchors keychain (
/System/Library/Keychains/X509Anchors and X509Certificates) when you open "Show Keychains" after launching Keychasin Access.app. You can also select Apple Root Certificate Authority therein to check whether the certificate is valid.
To begin with, identify where the cause lies with. It seems likely either .plist, caches, Keychain Access components, or the core system corruption. I recommend to remove file/s or folder/s to temporary folders on the desktop rather than trashing. To do so, you may reuse them after troubleshooting, if they are still needed.

/Library/Preferences/com.apple.SoftwareUpdate.plist
This preference stores the keys and their values stating about when Software Update.app lastly attempted to access the Software Update service, etc.
(b)
/Users/HOME/Library/Preferences/ByHost/com.apple.SoftwareUpdate.000xxxxxxxxx.pli st
This preference contains the key "AgreedToLicenseAgrement" for the value 1, and the key of "BackgroundDownload" as the value 0. The modified date and time of Get Info should be matched with the previous Security Update (e.g. 2005-007)
(c)
/Users/HOME/Library/Preferences/com.apple.SoftwareUpdate.plist
The modified date and time of Get Info will be set in between D/T for
loginwindow[xxx]: Login Window Started Security Agent and
kernel[0]: IPv6 packet filtering initialized, default to accept, logging disabled... Two lined events are indicated on system.log.

NOTE: You may be asked the admin password when removing/trashing "X509" files for the replacement. You need to find another computer which stores these intact files BEFORE restarting the computer.
[ Edited by Apple Discussions Moderator; please refrain from modifying X509 keychains ]
Make sure to back up "Software Update.log" before you do troubleshooting.
